TRANSILTM
FEATURES
PEAK PULSE POWER : 600 W (10/1000μs)
BREAKDOWN VOLTAGE RANGE :
From 6.8V to 220 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.
