UNI AND BIDIRECTIONAL TYPES LOW CLAMPING FACTOR FAST RESPONSE TIME JEDEC REGISTERED PACKAGE OUTLINE FEATURES SMA (JEDEC D0214 AC) Symbol Parameter Value Unit PPP Peak pulse power dissipation (see note 1) Tj initial = Tamb 400 W P Power dissipation on infinite heatsink Tamb = 50 °C3.3 W IFSM Non repetitive surge peak forward current for unidirectional types tp = 10ms Tj initial = Tamb 40 A Tstg Tj Storage temperature range Maximum junction temperature - 65 to + 175 150 °C °C TL Maximum lead temperature for soldering during 10 s. 260 °C Note 1 : For a surge greater than the maximum values, the diode will fail in short-circuit. ABSOLUTE MAXIMUM RATINGS (Tamb = 25°C) DESCRIPTION The SMAJ series are TRANSIL TM 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.
