DESCRIPTION
TheSMBJseries areTRANSIL
TM
diodesdesigned
specifically for protecting sensitive equipment
againsttransientovervoltages.
Transildiodes providehigh overvoltageprotection
by clamping action. Their instantaneousresponse
to transientovervoltages makes them particularly
suited to protect voltage sensitive devices such
as MOS Technology and low voltage supplied
IC’s.
