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 lead-
frame 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 10KV/µs. The use
of a proprietary dv/dt clamp results in a static dv/dt of
greater than 10KV/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 cur-
rent thyristors or TRIAC and relays.
Applications include solid-state relays, industrial con-
trols, office equipment, and consumer appliances.
