The IL421x consists of an Al Ga As IRLED optically coupled to a pair of photosensitive non-zero crossing SCR chips and are connected inversely parallel to form a TRIAC. These three semiconductors are assembled in a six pin 0.3 inch dual in-line package, using high insulation double molded, over/under leadframe construction. High input sensitivity is achieved by using an emitter follower phototransistor and a cascaded SCR predriver resulting in an LED trigger current of less than 1.3 m A (DC). The IL421x uses two discrete SCRs resulting in a mutating dv/dt of greater than 10KV/µs. The use of a proprietary dv/dt clamp results in a...
