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.
