JEDEC registered package outline

DESCRIPTION

The SMAJ series are TRANSIL^TMdiodes de-

signed specifically for protecting sensitive equip-

ment against transient overvoltages. The SMA

package allows save spacing on high density

printed circuit boards.

SMA

(JEDEC DO-214AC)

Table 1: Order Codes

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.
