MOC3010SR2M

Triac, SCR Output Optoisolators Overview

The MOC3010SR2M is a single-channel triac output optocoupler from onsemi, designed for random-phase triggering of AC power devices. It features a gallium arsenide infrared LED coupled to a photosensitive triac. The device provides electrical isolation with a rated insulation voltage of 5300 Vrms and supports peak off-state voltages up to 400 V. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.15 V, and a maximum trigger current of 5 mA. It operates within a temperature range of -40°C to +85°C and is available in a 6-pin SMD package.

• Designed for direct interface with logic circuits to drive triacs or SCRs

Triac, SCR Output Optoisolators Applications

• Solid-state relay (SSR) modules
• AC motor speed control circuits
• Lighting dimmer applications
• Heater control systems

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SR2M' to confirm the tape-and-reel packaging format and lead frame plating specifications. Ensure compatibility with surface-mount assembly processes given the 6-SMD gull-wing package type. Cross-reference the datasheet revision date to confirm parameter consistency, particularly regarding insulation voltage ratings and thermal characteristics, before finalizing component selection for production.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triggering is required rather than zero-crossing switching. The 400 V peak off-state voltage rating suits low-voltage AC applications. Consider the 5 mA maximum trigger current for driving circuit design. The SMD package facilitates automated assembly. Verify that the 5300 Vrms isolation rating meets the safety requirements of the target application environment.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC301x series of triac output optocouplers. It shares functional similarities with other members like the MOC3011 and MOC3012 but differs in peak voltage ratings and trigger current sensitivities. The SR2M designation indicates specific packaging and handling characteristics distinct from through-hole variants. It serves as a standard interface component between low-power control logic and high-power AC loads.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes include MOC3011SR2M and MOC3012SR2M from onsemi, provided voltage and trigger current requirements align. Generic equivalents may exist but require verification of insulation voltage and package dimensions. Ensure any replacement maintains the random-phase output characteristic and compatible 6-SMD footprint.
