Description

The IL420/ IL4208 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 semicon-

ductors are assembled in a six pin dual in-line pack-

age.

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

2.0 mA (DC)

The IL420/ IL4208 used two discrete SCRs resulting

in a commutating dV/dt of greater than 10 k/µs. The

use of a proprietary dV/dt clam results in a static dV/

dt of greater than 10 kV/µs. 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-

totransistors, disabling the firs stage SCR predriver

The 600/800 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/ IL4208 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.
