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 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 IL420/IL4208 used two discrete SCRs resulting in a
commutating dV/dt of greater than 10 kV/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
phototransistors, disabling the first stage SCR predriver.
The 600/800 V blocking voltage permits control of offline
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, solenoids, high current
thyristors or TRIAC and relays.
