DESCRIPTION

The IL420 consists of a GaAs IRLED optically coupled to a photosensi­tive non-zero crossing TRIAC network. The TRIAC consists of two
inverse parallel connected monolithic SCRs. 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 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 pho­totransistor, disabling the first stage SCR predriver.

The 600 V blocking voltage permits control of off-line voltages up to 240
V AC, 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 V AC lines to
control resistive, inductive, or capacitive loads including motors, sole­noids, high current thyristors or TRIAC and relays.

Applications include solid-state relays, industrial controls, office equip­ment, and consumer appliances.
