DESCRIPTION

The IL420 consists of a GaAs IRLED optically coupled to a photosensi- tive non-zero crossing TRIAC network. The TRIAC consists of two inverse parallel connected monolithic SCRs. These three semiconduc- tors 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 pho- totransistor and a cascaded SCR predriver resulting in an LED trigger current of less than 2 mA (DC). The IL420 uses two discrete SCRs resulting in a commutating dV/dt of greater than 10KV/ms. The use of a proprietary dv/dt clamp results in a static dV/dt of greater than 10KV/ms. This clamp circuit has a MOSFET that is enhanced when high dV/dt spikes occur between MT1 and MT2 of the TRIAC. When conducting, the FET clamps the base of the pho- totransistor, disabling the first stage SCR predriver. The 600 V blocking voltage permits control of off-line voltages up to 240 VAC, with a safety factor of more than two, and is sufficient for as much as 380 VAC. The IL420 isolates low-voltage logic from 120, 240, and 380 VAC lines to control resistive, inductive, or capacitive loads including motors, sole- noids, high current thyristors or TRIAC and relays. Applications include solid-state relays, industrial controls, office equip- ment, and consumer appliances.
