Optocoupler, Phototransistor Output, High Reliability, 5300 VRMS

DESCRIPTION

The SFH6156 features a variety of transfer ratios, low

coupling capacitance and high isolation voltage. This

coupler has a GaAs infrared diode emitter, which is optically

coupled to a silicon planar phototransistor detector, and is

incorporated in a plastic SMD package.

The coupling devices are designed for signal transmission

between two electrically separated circuits.

The coupler is end-stackable with 2.54 mm lead spacing.

Creepage and clearance distances of > 8 mm are achieved

with option 6. This version complies with IEC 60950

(DIN VDE0805) for reinforced insulation up to an operation

voltage of 400 VRMS or DC. Specifications subject to

change.

FEATURES

• Excellent CTR linearity depending on forward

current

• Isolation test voltage, 5300 VRMS

• Fast switching times

• Low CTR degradation

• Low coupling capacitance

• Compliant to RoHS Directive 2002/95/EC and in

accordance to WEEE 2002/96/EC

APPLICATIONS

• Switchmode power supply

•Telecom

• Battery powered equipment

AGENCY APPROVALS

• UL1577, file no. E52744 system code H or J, double

protection

Notes

• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not

implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute

maximum ratings for extended periods of the time can adversely affect reliability.

(1) Refer to reflow profile for soldering conditions for surface mounted devices (SMD).

Notes

• The thermal model is represented in the thermal network below. Each resistance value given in this model can be used to calculate the

temperatures at each node for a given operating condition. The thermal resistance from board to ambient will be dependent on the type of

PCB, layout and thickness of copper traces. For a detailed explanation of the thermal model, please reference Vishay’s thermal

characteristics of optocouplers application note.

• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering

evaluation. Typical values are for information only and are not part of the testing requirements.
