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.

APPLICATIONS
• Solid state relays
• Industrial controls
• Office equipment
• Consumer appliances
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.
AGENCY APPROVALS
• UL1577, file no. E52744 system code H, double protection
• CSA 93751
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 VAC
• DIN EN 60747-5-5 (VDE 0884), available with option 1
• CQC: GB8898-2001
.
The IL420, IL4208 isolates low-voltage logic from 120 VAC
,
240 VAC, and 380 VAC lines to control resistive, inductive, or
capacitive loads including motors, solenoids, high current
thyristors or TRIAC and relays.
