DESCRIPTION

The IL421x consists of an AlGaAs 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 pre-

driver resulting in an LED trigger current of less than

1.3 mA (DC).

The IL421x uses two discrete SCRs resulting in a

commutating dv/dt of greater than 10 kV/µs. The use

of a proprietary dv/dt clamp results in a static dv/dt of

greater than 10 kV/µs. This clamp circuit has a MOS-

FET that is enhanced when high dv/dt spikes occur

between MT1 and MT2 of the TRIAC. The FET clamps

the base of the phototransistor when conducting, dis-

abling the internal SCR predriver.

The blocking voltage of up to 800 V 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. Current handling capability is up to 300 mA

RMS, continuous at 25°C.

The IL421x isolates low-voltage logic from 120, 240,

and 380 VAC lines to control resistive inductive, or

capacitive loads including motors solenoids, high

current thyristors or TRIAC and relays.

Applications include solid-state relays, industrial con-

trols, office equipment, and consumer appliances.
