BZW50-10,B/180,B
TRANSIL
FEATURES
PEAK PULSEPOWER: 5000W (10/1000µs)
STAND-OFF VOLTAGERANGE:
From10V to 180V
UNI ANDBIDIRECTIONALTYPES
LOW CLAMPINGFACTOR
FASTRESPONSETIME
UL RECOGNIZED
DESCRIPTION
Transildiodes provide high overvoltageprotection
by clamping action. Their instantaneousresponse
to transientovervoltagesmakes them particularly
suited to protect voltage sensitive devices such
as MOS Technology and low voltage supplied
IC’s.
