MOC3062VM

Triac, SCR Output Optoisolators Overview

The MOC3062VM is a zero-crossing triac driver optocoupler from onsemi, housed in a 6-pin PDIP package. It features an infrared LED coupled to a hybrid triac output capable of driving discrete triacs. Key electrical parameters include a maximum forward voltage of 1.5V and a maximum input current of 60mA. The device offers high isolation with ratings of 7.5kVrms or 4.17kVrms depending on certification standards. It operates within a temperature range of -40°C to 85°C and includes logic output functionality for precise phase control applications.

Triac, SCR Output Optoisolators Feature Summary

• Zero-crossing detection ensures low electromagnetic interference during switching
• Snubberless design allows direct drive of discrete triacs without external snubber circuits
• High isolation voltage provides robust safety between control and power sides

Triac, SCR Output Optoisolators Applications

• Solid-state relay (SSR) inputs
• Motor speed control systems
• Lighting dimmer circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific isolation voltage rating required by your application design, as datasheets may list 4.17kVrms or 7.5kVrms based on regional certification bodies such as VDE or UL. Confirm that the DIP-6 through-hole package aligns with your PCB layout constraints. Ensure the 60mA maximum input current specification is compatible with your microcontroller or logic gate output capabilities to prevent component damage.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is mandatory to minimize electrical noise and inrush current stress on the load. The snubberless feature simplifies circuit design by reducing component count compared to non-zero-crossing alternatives. Consider the 60mA input current requirement to ensure adequate drive strength from the controlling logic source. Verify thermal management needs for the 250mW power dissipation rating in enclosed environments.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3 series of Optotriacs, designed specifically for AC power control applications. It complements other variants like the MOC3062M and MOC3063SR2VM, differing primarily in packaging and specific isolation certifications. The series is widely used in industrial automation and consumer electronics where reliable AC switching and galvanic isolation are critical requirements.

Triac, SCR Output Optoisolators Replacement Considerations

The MOC3062M is a pin-compatible alternative in the same series but may differ in isolation certification ratings. Verify that any substitute maintains the zero-crossing characteristic and snubberless capability. Check if the replacement part meets the same 600V output voltage rating and operating temperature range to ensure functional equivalence in existing designs.
