1.5KE6V8A/440A
1.5KE6V8CA/440CA
TRANSILTM
FEATURES
PEAK PULSE POWER : 1500 W (10/1000µs)
BREAKDOWN VOLTAGE RANGE :
From6.8V to 440 V
UNI AND BIDIRECTIONALTYPES
LOWCLAMPING FACTOR
FAST RESPONSETIME
UL RECOGNIZED
DESCRIPTION
Transil diodes provide high overvoltage protection
by clamping action. Their instantaneousresponse
to transient overvoltages makes them particularly
suited to protect voltage sensitive devices such
as MOSTechnologyand lowvoltagesupplied IC’s.
