SCR thyristor handles 600V 40Arms, 150°C junction temperature

LITTELFUSE SJxx40x Series of 40A standard high-temperature silicon-controlled rectifier (SCR) thyristors are capable of handling 600V, 40Arms and junction temperatures up to 150°C. Devices prevent the overheating and thermal runaway problems SCRs can experience due to an application’s limited cooling capability or occasional overload situation. Products trigger with just a few milli-amps of current at less than 1.5V potential. http://www.Littelfuse.com
