DESCRIPTION
The IL411x consists of an AlGaAs IRLED optically
coupled to a photosensitive zero crossing TRIAC
network. The TRIAC consists of two inverse parallel
connected monolithic SCRs. These three semicon-
ductors 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 emit-
ter follower phototransistor and a cascaded SCR
predriver resulting in an LED trigger current of less
than 1.3 mA(DC).
The IL411x uses two discrete SCRs resulting in a
commutating dV/dt greater than 10 KV/ms 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 pho-
totransistor, disabling the first stage SCR predriver.
The zero cross line voltage detection circuit con-
sists of two enhancement MOSFETS and a photo-
diode. The inhibit voltage of the network is
determined by the enhancement voltage of the N-
channel FET. The P-channel FET is enabled by a
photocurrent source that permits the FET to con-
duct the main voltage to gate on the N-channel FET.
Once the main voltage can enable the N-channel, it
clamps the base of the phototransistor, disabling
the first stage SCR predriver.
The blocking voltage of up to 800 V permits control
of off-line voltages up to 240 VAC, with a safety fac-
tor 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 IL411x 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 equipment, and consumer appli-
ances.
