41206ESDA-TR1 - Cooper Bussmann

41206ESDA, Four Element

Array Chip, Polymer ESD

Suppressor With SurgX®Technology

The ESDA product family with SurgX®Technology is

specifically designed to protect sensitive electronic circuits

from the threat of electrostatic discharge (ESD). 4-line array

can protect up to 4 isolated lines simultaneously with perfor-

mance similar to individual chip devices.ESDAdevices react

almost instantaneously to the transient voltage and effectively

clamp it in an average of 35V for the duration of the ESD tran-

sient, meaning less voltage stress during the clamp period and

greater IC protection. The design of ESDA series inherently

produces an ultralowcapacitance part. In the off state the

product is virtually invisible to the circuit. Installed from signal

line to ground, it is especially transparent to the high-speed

digital circuits due to the high off-state impedance and low

capacitance. Signals are not distorted or disrupted as shown

by extensive testing. With ESDA series, waveform definition

stays true and high-speed signals do not suffer. ESDA series

utilizeaunique polymer-based material. The nature of the

material creates a bi-directional part, which means that only

one device is required to provide complete ESD protection

regardless of the surge polarity.The combination of this mate-

rial with proven thick film on ceramic technology produces a

reliable,surface mount product that will help protect mobile

communications, computers, data processing, test equipment,

and manyother electronic applications from ESD.

Notes:

1. The product is 100% tested for 30V operating voltage at 25°C.

Continuous operation with higher than 12VDC under extreme

temperature and humidity may cause increasing leakage cur-

rent and/or shifting device resistance. However, even under

severe environmental test, characteristics of the device did not

change up to 12VDC operation.

2. Some shifting in characteristics may occur when tested over

several hundred ESD pulses at very rapid rate of 1 pulse per

second or faster.

3. Per IEC 61000-4-2, 30A @ 8kV, level 4, clamp measurement

made 30 ns after initiation of pulse,all tests in contact dis-

charge mode.

4. Trigger measurement made using Transmission Line Pulse

(TLP) method.

5. PolySurg™ devices are capable of withstanding up to a 15 kV,

45A ESD pulse. Device ratings are given at 8kV per Note 1,

unless otherwise specified.

Device Marking

ESDA devices are marked on the tape and reel packages, not individually. Since the product is bi-directional and symmetrical, no

orientation marking is required.

Device Application

ESDA series are applicable to most signal line circuits. It is applied in a shunt-connected manner. They are not suitable for use on

lines where lighting or load-switching transients are present. ESDA series is ideal for use in computers and computer-related equip-

ment, such as modems, keyboards, and printers. ESDA series is also well suited for portable electronic equipment such as mobile

telephones, test equipment, and card scanners.

Processing Recommendations

ESDA series currently have a convex profile on the top surface of the part. This profile is a result of the construction of the device.

Theycan be processed using standard pick – and – place equipment. The placement and processing techniques for ESDA series

are similar to those used for chip resistors and chip capacitors

The Location in the circuit for the ESDA series has to be carefully determined. For the better performance of the device, the device

should be positioned as close to the signal input as possible and ahead of any other component.
