VO3023-X001

Triac, SCR Output Optoisolators Overview

The VO3023-X001 is a single-channel phototriac output optoisolator manufactured by Vishay Semiconductor Opto Division. It provides electrical isolation between low-voltage control circuits and high-voltage AC loads. The device features a 5000Vrms isolation voltage rating and supports a peak repetitive off-state voltage of 400V. Key electrical parameters include a typical forward voltage of 1.3V, a maximum DC forward current of 50mA, and a minimum common-mode transient immunity of 100V/µs. It operates within a temperature range of -40°C to 100°C and is housed in a 6-DIP through-hole package.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm pinout and packaging variations. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the supplier source matches the manufacturer's authorized distribution network to avoid counterfeit components. Check for any recent Product Change Notifications regarding manufacturing site transfers or material updates.

Triac, SCR Output Optoisolators Selection Notes

Select this component when interfacing microcontrollers with AC mains or industrial AC loads requiring galvanic isolation. The phototriac output is suitable for driving triacs or SCRs directly. Consider the 400V blocking voltage limit for low-to-medium voltage AC applications. The DIP-6 package facilitates easy prototyping and through-hole assembly in standard enclosures.

Triac, SCR Output Optoisolators Part Context

This part belongs to the VO302x series of Vishay optocouplers, which are specialized for zero-crossing detection and AC power control. The series is designed to minimize electromagnetic interference during switching events. The VO3023 variant specifically integrates a phototriac detector on the input side to ensure turn-on only near the AC voltage zero-crossing point.
