MOC3023S-TA1

Triac, SCR Output Optoisolators Overview

The MOC3023S-TA1 is a single-channel Triac and SCR output optocoupler manufactured by Lite-On. It features an SMD-6 Gull Wing package designed for surface mount applications. The device provides an isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum forward current of 50 mA, a forward voltage of 1.15 V, and power dissipation of 330 mW. It operates without a zero-crossing circuit and supports a peak off-state voltage (Vdrm) of 400 V. The component functions within a temperature range of -40°C to +100°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix TA1 against manufacturer datasheets to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and relevant safety certifications such as UL, CSA, and VDE before integration into certified equipment designs.

Triac, SCR Output Optoisolators Selection Notes

Select this component when surface mount technology is required for isolated AC switching. The absence of a zero-crossing circuit makes it suitable for phase-angle control applications where precise timing is necessary rather than noise reduction.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3023 series of Triac driver optocouplers. It shares functional similarities with through-hole variants but utilizes a compact SMD-6 footprint. The series is widely used in general-purpose AC load control applications requiring galvanic isolation.

Triac, SCR Output Optoisolators Replacement Considerations

Cross-reference with MOC3023M for alternative packaging options. Verify pinout compatibility and thermal characteristics when substituting with other Triac output optocouplers from different manufacturers.
