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.

The ITA series combines high surge capability against energetic pulses with high voltage performance against ESD.

The separated input/output configuration of the device ensures improved protection against very fast transient overvoltage like ESD by elimination of the spikes induced by parasitic inductances created by external wiring.

FEATURES

■ High surge capability Transil array:

IPP = 40 A (8/20μs)

■ Peak pulse power : 300 W (8/20μs)

■ Separated Input - Output

■ Up to 9 bidirectional Transil functions

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

■ Low leakage current

■ ESD protection up to 15kV

MAIN APPLICATIONS

Differential data transmission lines protection, such as :

■ RS-232

■ RS-423

■ RS-422

■ RS-485
