Description

Transil diode arrays ITA25B1 provide high overvoltage protection by clamping action. Their instantaneous ITA25B1 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 ITA25B1 allies high surge capability against energetic pulses with high voltage performance against ESD.
