1.5KE6V8A/440A
FEATURES
■ PEAK PULSE POWER : 1500 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 providehigh overvoltage protection
by clampingaction. 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.
