Description

Transil diode arrays ITA25B3 provide high overvoltage protection by clamping action. Their instantaneous ITA25B3 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 ITA25B3 allies high surge capability against energetic pulses with high voltage performance against ESD.

The separated input/output configuration of the ITA25B3 ensures improved protection against very fast transient overvoltage like ESD by elimination of the spikes induced by parasitic inductances created by external wiring.
