BT137-600D
4Q Triac
Rev.01 - 15 March 2018 Product data sheet
1. General description
Planar passivated very sensitive gate four quadrant triac in a SOT78 (TO-220AB) plastic
package intended for use in general purpose bidirectional switching and phase control
applications, where high sensitivity is required in all four quadrants. This very sensitive
gate "series D" triac is intended to be interfaced directly to microcontrollers, logic
integrated circuits and other low power gate trigger circuits.
2. Features and benets
• High blocking voltage capability
• Direct triggering from low power drivers and logic ICs
• Planar passivated for voltage ruggedness and reliability
• Triggering in all four quadrants
• Low holding current for low current loads and lowest EMI at commutation
• Very sensitive gate
3. Applications
• General purpose motor control
• General purpose switching

Definitions
Draft — The document is a draft version only. The content is still under
internal review and subject to formal approval, which may result in
modifications or additions. WeEn Semiconductors does not give any
representations or warranties as to the accuracy or completeness of
information included herein and shall have no liability for the consequences
of use of such information.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is
intended for quick reference only and should not be relied upon to contain
detailed and full information. For detailed and full information see the
relevant full data sheet, which is available on request via the local WeEn
Semiconductors sales office. In case of any inconsistency or conflict with the
short data sheet, the full data sheet shall prevail.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
WeEn Semiconductors and its customer, unless WeEn Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the WeEn Semiconductors product
is deemed to offer functions and qualities beyond those described in the
Product data sheet.
Disclaimers
Limited warranty and liability — Information in this document is believed
to be accurate and reliable. However, WeEn Semiconductors does not
give any representations or warranties, expressed or implied, as to the
accuracy or completeness of such information and shall have no liability for
the consequences of use of such information. WeEn Semiconductors takes
no responsibility for the content in this document if provided by an information
source outside of WeEn Semiconductors.
In no event shall WeEn Semiconductors be liable for any indirect, incidental,
punitive, special or consequential damages (including - without limitation -
lost profits, lost savings, business interruption, costs related to the removal
or replacement of any products or rework charges) whether or not such
damages are based on tort (including negligence), warranty, breach of
contract or any other legal theory.
Notwithstanding any damages that customer might incur for any reason
whatsoever, WeEn Semiconductors’ aggregate and cumulative liability
towards customer for the products described herein shall be limited in
accordance with the Terms and conditions of commercial sale of WeEn
Semiconductors.
Right to make changes — WeEn Semiconductors reserves the right to
make changes to information published in this document, including without
limitation specifications and product descriptions, at any time and without
notice. This document supersedes and replaces all information supplied prior
to the publication hereof.
Suitability for use — WeEn Semiconductors products are not designed,
authorized or warranted to be suitable for use in life support, life-critical
or safety-critical systems or equipment, nor in applications where failure
or malfunction of an WeEn Semiconductors product can reasonably
be expected to result in personal injury, death or severe property or
environmental damage. WeEn Semiconductors and its suppliers accept no
liability for inclusion and/or use of WeEn Semiconductors products in such
equipment or applications and therefore such inclusion and/or use is at the
customer’s own risk.
Quick reference data — The Quick reference data is an extract of the
product data given in the Limiting values and Characteristics sections of this
document, and as such is not complete, exhaustive or legally binding.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. WeEn Semiconductors makes
no representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using WeEn Semiconductors products, and WeEn
Semiconductors accepts no liability for any assistance with applications or
customer product design. It is customer’s sole responsibility to determine
whether the WeEn Semiconductors product is suitable and fit for the
customer’s applications and products planned, as well as for the planned
application and use of customer’s third party customer(s). Customers should
provide appropriate design and operating safeguards to minimize the risks
associated with their applications and products.
WeEn Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default
in the customer’s applications or products, or the application or use by
customer’s third party customer(s). Customer is responsible for doing all
necessary testing for the customer’s applications and products using WeEn
Semiconductors products in order to avoid a default of the applications
and the products or of the application or use by customer’s third party
customer(s). WeEn does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
No offer to sell or license — Nothing in this document may be interpreted
or construed as an offer to sell products that is open for acceptance or the
grant, conveyance or implication of any license under any copyrights, patents
or other industrial or intellectual property rights.
Export control — This document as well as the item(s) described herein
may be subject to export control regulations. Export might require a prior
authorization from competent authorities.
Non-automotive qualified products — Unless this data sheet expressly
states that this specific WeEn Semiconductors product is automotive
qualified, the product is not suitable for automotive use. It is neither qualified
nor tested in accordance with automotive testing or application requirements.
WeEn Semiconductors accepts no liability for inclusion and/or use of non-
automotive qualified products in automotive equipment or applications.
In the event that customer uses the product for design-in and use in
automotive applications to automotive specifications and standards,
customer (a) shall use the product without WeEn Semiconductors’ warranty
of the product for such automotive applications, use and specifications, and
(b) whenever customer uses the product for automotive applications beyond
WeEn Semiconductors’ specifications such use shall be solely at customer’s
own risk, and (c) customer fully indemnifies WeEn Semiconductors for
any liability, damages or failed product claims resulting from customer
design and use of the product for automotive applications beyond WeEn
Semiconductors’ standard warranty and WeEn Semiconductors’ product
specifications.
