SMAJ
TRANSILTM

FEATURES Peak Pulse Power : 400 W (10/1000us) Stand off voltage range: From 5V to 188V Uni and Bidirectional types Low clamping factor Fast response time 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. Table 2: Absolute Maximum Rating (Tamb = 25 C) Symbol PPP P IFSM Tstg Tj TL Parameter Peak pulse power dissipation (see note 1) Power dissipation on infinite heatsink Non repetitive surge peak forward current for unidirectional types Storage temperature range Maximum junction temperature Maximum lead temperature for soldering during 10 s.
