MOC3023S

Triac, SCR Output Optoisolators Overview

The MOC3023S is a Triac and SCR output optocoupler manufactured by Lite-On Inc. It features a six-pin SMD package with gull-wing leads, designed for surface mount applications. The device provides one channel of isolation with an insulation voltage of 5000 Vrms. It operates without a zero-crossing circuit, allowing for phase control applications. Key electrical parameters include a maximum forward current of 50 mA, a forward voltage of 1.15 V, and power dissipation of 330 mW. The component supports a peak off-state output voltage (Vdrm) of 400 V and functions within a temperature range of -40°C to +100°C.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage isolation between input and output circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'S' confirms the surface mount gull-wing package variant rather than the through-hole DIP version. Confirm RoHS compliance status as indicated in official documentation. Ensure the absence of zero-crossing detection aligns with the intended phase-control application requirements before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when surface mount technology is required for triac triggering. The non-zero-crossing design is suitable for applications requiring precise phase-angle control rather than noise reduction at AC transitions. Verify that the 400 V off-state voltage rating meets the load voltage requirements of the target circuit design.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC30 series of Triac and SCR output optoisolators from Lite-On. It serves as a solid-state switching interface, electrically isolating low-voltage control logic from high-voltage AC loads. The SMD variant facilitates automated assembly processes in modern electronics manufacturing.
