High temperature SCR (silicon-controlled rectifier) thyristors offer a junction temperature of 302°F (150°C) in compact surface-mount D-Pak (TO-252) packaging. These devices are also available in through-hole V-Pak (TO-251) packages. Standard SJ Series SCR thyristors have a low gate current trigger level of 6 or 15 mA maximum at approximately 1.5 V. Sensitive models in the series feature a gate trigger current of less than 200 µA. The sensitive gate devices can be triggered by sense coils, proximity switches and microprocessors.
