TRANSIL
TM
FEATURES
PEAK PULSE POWER : 600 W (10/1000µs)
BREAKDOWN VOLTAGE RANGE :
From 6.8V to 440 V.
UNI AND BIDIRECTIONAL TYPES.
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.
