FEATURES
PEAK PULSE POWER : 1500 W (10/1000碌s)
STAND OFF VOLTAGE RANGE :
From 5V to 188V.
UNI AND BIDIRECTIONAL TYPES
LOW CLAMPING FACTOR
FAST RESPONSE TIME
DESCRIPTION
The SMCJ series are TRANSIL
TM
diodes designed
specifically for protecting sensitive equipment
against transient overvoltages.
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鈥檚.
