DESCRIPTION
The IL420/4208 consists of a GaAs IRLED optically coupled to a photo-
sensitive non-zero crossing TRIAC network. The TRIAC consists of two
inverse parallel connected monolithic SCRs. These three semiconduc-
tors 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 pho-
totransistor and a cascaded SCR predriver resulting in an LED trigger
current of less than 2.0 mA (DC).
The IL420/4208 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
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 600/800 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 IL420/4208 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 controls, office equip-
ment, and consumer appliances.
