DESCRIPTION
The IL410/IL4108 consists of a GaAs IRLED optically
coupled to a photosensitive zero crossing TRIAC network.
The TRIAC consists of two inverse parallel connected
monolithic SCRs. These three semiconductors are
assembled in a six pin dual in-line package.
High input sensitivity is achieved by using an emitter follower
phototransistor and a cascaded SCR predriver resulting in
an LED trigger current of less than 2.0 mA (DC).
The IL410/IL4108 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/ms. 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 zero cross line voltage detection circuit consists of two
enhancement MOSFETS and a photodiode. 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 conduct 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 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 IL410/IL4108 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.
