MOC3052TVM

Triac, SCR Output Optoisolators Overview

The MOC3052TVM is a random-phase triac driver optocoupler featuring an infrared emitting diode optically coupled to a non-zero-crossing silicon bilateral AC switch. It provides electrical isolation between low-voltage logic circuits and high-voltage AC loads. Key parameters include a peak blocking voltage of 600 V, an isolation voltage of 7500 V, and a maximum forward current of 60 mA. The device operates within a temperature range of -40 °C to +85 °C and utilizes a 6-pin DIP package for through-hole mounting.

Triac, SCR Output Optoisolators Feature Summary

• Random-phase triggering capability for precise AC load control without zero-crossing detection

Triac, SCR Output Optoisolators Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or onsemi, noting that onsemi acquired Fairchild's semiconductor business. Confirm the specific suffix 'TVM' corresponds to the correct tape-and-reel packaging configuration. Ensure compliance with RoHS standards and check for UL recognition and VDE approval markings on the component body to validate safety certifications.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase firing is required rather than zero-crossing switching. It is suitable for applications involving inductive loads due to its enhanced dv/dt stability. Consider the 600 V peak blocking voltage limit and ensure the isolation requirements do not exceed the specified 7500 V rating. Verify that the DIP-6 through-hole package fits the target PCB layout constraints.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC3051M/MOC3052M series of 6-pin DIP random-phase optoisolators. These components are designed to isolate low-voltage logic from 115 V AC and 240 V AC mains voltages. The series offers excellent IFT stability and is widely used in general-purpose AC power control applications requiring reliable triac driving capabilities.

Triac, SCR Output Optoisolators Replacement Considerations

The MOC3052S-M is a comparable alternative from Fairchild/ON Semiconductor. Verify pinout compatibility and electrical parameter equivalence before substitution.
