MOC3022SR2VM

Triac, SCR Output Optoisolators Overview

The MOC3022SR2VM is a random-phase triac driver optocoupler manufactured by Fairchild Semiconductor. It features an aluminum gallium arsenide infrared emitting diode coupled to a light-activated silicon bilateral switch. The device provides electrical isolation for interfacing electronic controls with power triacs in AC line applications. Key parameters include a peak off-state voltage of 400 V, an isolation voltage of 5300 Vrms, and a maximum forward current of 60 mA. It operates within a temperature range of -40°C to +85°C and is housed in a 6-SMD gull-wing package.

Triac, SCR Output Optoisolators Feature Summary

• Integrates an AlGaAs infrared LED with a light-activated silicon bilateral switch for robust optical coupling.
• Provides high-voltage isolation between control circuits and power triacs without zero-crossing detection.
• Designed for reliable triggering of triacs in resistive and inductive load applications.

Triac, SCR Output Optoisolators Applications

• Interfacing electronic controls with power triacs for AC line operation.
• Controlling resistive loads in solid-state relays.
• Driving inductive loads in industrial automation systems.

Triac, SCR Output Optoisolators Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or onsemi, as corporate transitions may affect labeling. Confirm the suffix SR2VM corresponds to the specific 6-SMD gull-wing surface mount package variant. Ensure compliance with RoHS directives and check for any recent Product Change Notifications (PCN) regarding assembly or material updates prior to finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triggering is required rather than zero-crossing switching. The 400V peak off-state voltage rating suits standard 115/240VAC operations. Consider the 6-SMD package for automated surface mount assembly processes. Verify that the 10mA maximum trigger current aligns with the driving circuit's output capabilities for reliable triac activation.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC302XM series of 6-pin DIP and SMD random-phase optoisolators. It shares functional similarities with the MOC3020M and MOC3023M but differs in packaging and specific trigger characteristics. The series is widely used in general-purpose AC power control applications requiring galvanic isolation between low-voltage logic and high-voltage AC lines.

Triac, SCR Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers include MOC3022VM for through-hole equivalents. Cross-reference datasheets for pinout compatibility and electrical parameter alignment before substitution.
