SM15T6V8CA/220CA
TRANSILTM
FEATURES
s PEAK PULSE POWER : 1500 W (10/1000µs)
s BREAKDOWN VOLTAGE RANGE :
From 6.8 V to 220 V
s UNI AND BIDIRECTIONAL TYPES
s LOW CLAMPING FACTOR
s FAST RESPONSE TIME
s 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.
