JEDEC REGISTERED PACKAGE OUTLINE
DESCRIPTION
The SMAJ series are TRANSILTM diodes designed
specifically for protecting sensitive equipment
against transient overvoltages. The SMA package
allows save spacing on high density printed circuit
boards.
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.
