MOC3051FVM

Triac, SCR Output Optoisolators Overview

The MOC3051FVM is a Triac output optoisolator featuring a 6-SMD package. It provides an isolation voltage of 7500Vpk and supports a peak off-state voltage of 600 V. The device operates within a temperature range of -40°C to 85°C. Key electrical parameters include a maximum DC forward current of 60 mA, a typical forward voltage of 1.15 V, and a minimum static dV/dt of 1 kV/µs. It lacks zero-crossing circuitry and utilizes a non-zero-crossing trigger mechanism.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'FVM' corresponds to the 6-SMD surface-mount configuration and 7500Vpk isolation rating. Confirm that the absence of zero-crossing detection aligns with the intended noise immunity requirements of the application design.

Triac, SCR Output Optoisolators Selection Notes

Select this component when high isolation voltage is required in a small footprint. Ensure the load current does not exceed the external TRIAC's rating. Consider thermal management for the host TRIAC if operating at high duty cycles or ambient temperatures near the upper limit.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC305x series of Triac driver optoisolators from onsemi. It shares functional similarities with other members like the MOC3051M but differs in packaging and isolation specifications. The series is widely used for triggering TRIACs in industrial and consumer AC control applications.

Triac, SCR Output Optoisolators Replacement Considerations

Cross-reference with MOC3052FVM for zero-crossing functionality. Verify pinout compatibility with existing PCB layouts before substituting with other Triac output optoisolators.
