DESCRIPTION
The IL420 and 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 mA (DC).
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 V, 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 V
AC
.
The IL420, IL4208 isolates low-voltage logic from 120 V
AC
,
240 V
AC
, and 380 V
AC
lines to control resistive, inductive, or
capacitive loads including motors, solenoids, high current
thyristors or TRIAC and relays.

• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
