Littelfuse says it can supply a silicon-controlled rectifier (SCR) thyristor circuit protection device with a junction temperature of 150°C in a surface-mount package. The SJ series thyristors have a low gate current trigger level of 6mA or 15mA maximum at approximately 1.5V. The most sensitive devices feature a gate trigger current of less than 200μA, ...
