| (R) SM6HTxxA HIGH TEMPERATURE TRANSILTM FOR AUTOMOTIVE APPLICATIONS FEATURES HIGH PERFORMANCE TRANSIL DESIGNED TO FIT HIGH TEMPERATURE ENVIRONMENT LIKE AUTOMOTIVE APPLICATIONS... HIGH RELIABILITY PLANAR TECHNOLOGY HIGH PERFORMANCE IN VOLTAGE REGULATION MODE VERY LOW LEAKAGE CURRENT (IR max = 5A @ Tamb = 150C) PEAK PULSE POWER : 600 W (10/1000s) FAST RESPONSE TIME UNIDIRECTIONAL TYPE LOW CLAMPING FACTOR DESCRIPTION This high performance Transil series has been designed to fit high temperature environment such as automotive applications, using surface mount technology. These devices are using high reliability planar technology resulting in high performances in voltage regulation mode and low leakage current at high temperature. ABSOLUTE MAXIMUM RATINGS (Tamb = 25C) 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 Tj initial = Tamb Tamb = 50C tp = 10ms Tj initial = Tamb Value 600 5 75 - 65 to 175 260 Unit W W A C C SMB (JEDEC D0-214AA) Storage and operating junction temperature range Maximum lead temperature for soldering during 10 s. Note 1 : For a surge greater than the maximum values, the diode will fail in short-circuit. THERMAL RESISTANCES Symbol Rth (j-l) Rth (j-a) Junction to leads Junction to ambient on printed circuit.
