IL420-X006

Overview

The Vishay IL420-X006 is a single-channel phototriac output optocoupler housed in a 6-pin PDIP package. It provides an isolation voltage of 5300 Vrms and supports a maximum continuous output current of 300 mA with a blocking voltage of 600 V. The device features a low input forward current of 1.6 mA and a typical forward voltage of 1.2 V. Operating temperatures range from -55°C to +100°C, and it lacks a zero-crossing circuit.

Feature Summary

• Non-zero crossing triac output for flexible phase control applications
• High dV/dt immunity to prevent false triggering in noisy environments
• Low LED trigger current reduces power consumption on the input side

Applications

• Solid-state relay (SSR) driver circuits
• AC motor speed control systems
• General-purpose AC load switching

Procurement Notes

Verify that the specific suffix X006 corresponds to the tube packaging format rather than tape and reel variants like X007T. Confirm the non-zero crossing characteristic aligns with your phase-control requirements, as this differs from zero-crossing devices. Ensure the 600 V blocking voltage meets the peak line voltage specifications of your target application.

Selection Notes

Select this component when high isolation voltage and fast response are required without the timing constraints of zero-crossing detection. The low input current allows direct interfacing with standard logic outputs or microcontrollers without additional drive circuitry. Consider the thermal dissipation capabilities if operating near the upper temperature limits.

Part Context

This part belongs to the IL420 series of Vishay phototriac optocouplers, designed for robust industrial isolation. It serves as a bridge between low-voltage control electronics and high-voltage AC loads. The series is recognized for its reliability in harsh electrical environments requiring strict galvanic isolation standards.

Replacement Considerations

The VO4256D-X006 is a documented substitute within the same manufacturer family. Verify pinout compatibility and ensure the replacement maintains the required 5300 Vrms isolation rating and 300 mA output current capacity.
