LOW CLAMPING FACTOR
FAST RESPONSE TIME
UL RECOGNIZED
DESCRIPTION
Transil diodes 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.
