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 particu­larly suited to protect voltage sensitive devices
such as MOS Technology and low voltage sup­plied IC’s.
