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.
