DESCRIPTION
Transil diode arrays provide high overvoltage
protectionby clamping action.Theirinstantaneous
response to transient overvoltages makes them
particularly suited to protect voltage sensitive
devicessuch as MOS Technologyand low voltage
suppliedIC’s.
The ITA series allies highsurge capabilityagainst
energetic pulses with high voltage performance
againstESD.
