| (R) SM6T6V8A/220A SM6T6V8CA/220CA TRANSILTM FEATURES s s s s s s PEAK PULSE POWER : 600 W (10/1000s) BREAKDOWN VOLTAGE RANGE : From 6.8V 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. ABSOLUTE MAXIMUM RATINGS (Tamb = 25C) Symbol PPP P IFSM 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.
