1.5KE6V8CA/440CA
TRANSILTM
FEATURES
s PEAK PULSE POWER : 1500 W (10/1000µs)
s BREAKDOWN VOLTAGE RANGE :
From 6.8V to 440 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.

Parameter
PPP
Peak pulse power dissipation (see note 1) Tj initial = Tamb
P
Power dissipation on infinite heatsink
Tamb = 75°C
IFSM
Non repetitive surge peak forward current tp = 10ms
for unidirectional types
Tj initial = Tamb
Tstg
