FUNCTIONAL DIAGRAM
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 allies high surge capability against
energetic pulses with high voltage performance
against ESD.
