JEDEC REGISTERED PACKAGE OUTLINEDESCRIPTION

The SMAJ series are TRANSILTM diodes designedspecifically for protecting sensitive equipmentagainst transient overvoltages. The SMA packageallows save spacing on high density printed circuitboards.

Transil diodes provide high overvoltage protectionby clamping action. Their instantaneous responseto transient overvoltages makes them particularlysuited to protect voltage sensitive devices suchas MOS Technology and low voltage suppliedIC’s.
