Description

Transil diode arrays ITA18B1 provide high overvoltage protection by clamping action. Their instantaneous ITA18B1 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 ITA18B1 allies high surge capability against energetic pulses with high voltage performance against ESD.
