1 / 9 page February 2007 Rev 4 1/9 9 SM15T TRANSIL™ Features ■ Peak pulse power: 1500 W (10/1000 µs) ■ Breakdown voltage range: from 6.8 V to 220 V ■ Uni and bidirectional types ■ Low clamping factor ■ Fast response time ■ UL recognized Description 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. Order code TM: TRANSIL is a trademark of STMicroelectronics Part number Marking SM15TxxxA See Table 5 on page 7 SM15TxxxCA See Table 5 on page 7 K A Unidirectional Bidirectional SMC (JEDEC DO-214AB) Table 1. Absolute maximum ratings (Tamb = 25° C) Symbol Parameter Value Unit PPP Peak pulse power dissipation(1) Tj initial = Tamb 1500 W P Power dissipation on infinite heatsink Tamb = 50° C 6.5 W IFSM Non repetitive surge peak forward current for unidirectional types tp = 10ms Tj initial = Tamb 200 A Tstg Storage temperature range -65 to + 175 °C Tj Maximum operating junction temperature 150 °C TL Maximum lead temperature for soldering during 10 s. 260 °C 1. For a surge greater than the maximum values, the diode will fail in short-circuit. Table 2.
