描述 Description

Transil diode arrays provide high overvoltage protection by clamping action. Their instantaneous response to transient overvoltages makes them particularly suited to protect voltage sensitive devices such as MOS technology and low voltage supplied IC’s.

特性 Features

■ High surge capability Transil array: IPP = 40 A (8/20 µs)

■ Peak pulse power: 300 W (8/20 µs)

■ Up to 5 bidirectional Transil functions

■ Low clamping factor (VCL / VBR) at high current level

■ Low leakage current

■ ESD protection up to 15 kV

Complies with the following standards

■ IEC 61000-4-2 level 4

– 15 kV (air discharge)

– 8 kV (contact discharge)

■ MIL STD 883G- Method 3015-7: class 3B

– 25 kV (human body model)

Applications

Differential data transmission line protection, such as:

■ RS-232

■ RS-423

■ RS-422

■ RS-485
