DESCRIPTION
The SMBJ series are TRANSIL^TM diodes designed
specifically for protecting sensitive equipment
against transient overvoltages.
Transil diodes provide high overvoltage protection
by clamping action. Their instantaneous response
to transient overvoltages makes them particu-
larly suited to protect voltage sensitive devices
such as MOS Technology and low voltage sup-
plied IC’s.
