IL4118 Description

Short technical summary and product information.

The IL4118 is an optocoupler from Vishay Semiconductors, part of the IL4116, IL4117, and IL4118 product family. It integrates a GaAs IRLED with a photosensitive thyristor system, including noise suppression and a zero crossing circuit. This design enables low trigger currents of 0.7 mA and supports load voltages up to 800 V with a high dV/dt ratio of greater than 10 kV/μs.

 

This optocoupler is a microcontroller-friendly solution for isolating low-voltage logic from high-voltage AC lines (120 V, 240 V, and 380 VAC). It is suitable for controlling various AC loads such as motors, solenoids, high-power thyristors or TRIACs, and solid-state relays. Applications include solid-state relays, lighting controls, temperature controls, solenoid/valve controls, and AC motor drives/starters.

 

The IL4118 is available in DIP-6 and SMD-6 packages. Agency approvals include UL, cUL, DIN EN 60747-5-5 (VDE 0884-5), and FIMKO. Options for tape and reel packaging are also available.
