MOC3010TM

Triac, SCR Output Optoisolators Overview

The MOC3010TM is a single-channel Triac and SCR output optocoupler from onsemi, designed for zero-crossing detection applications. It features a PhotoTriac output capable of triggering triacs or SCRs in AC power control circuits. The device provides electrical isolation with an insulation voltage of 4170 Vrms. Key electrical parameters include a maximum forward current of 60 mA, a forward voltage of 1.5 V, and a peak repetitive off-state voltage (VDRM) of 250 V. It operates within a temperature range of -40°C to +85°C and is housed in a standard 6-pin DIP package.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'TM' against the official datasheet to confirm pinout and mechanical dimensions match the design requirements. Ensure that the zero-crossing feature aligns with the system's timing constraints. Confirm compliance with relevant safety standards such as UL1577 or IEC60747-5-5 if required by the end application.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize noise and inrush current. Compare the 250 V VDRM rating against the peak line voltage to ensure adequate margin. Consider the 60 mA input current requirement for the LED side when designing the drive circuitry. Evaluate thermal dissipation needs based on the specified power dissipation limits.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC30 series of Triac and SCR output optocouplers. It is functionally similar to the MOC3010M but may differ in packaging or specific manufacturing lot characteristics defined by the suffix. It serves as a key interface component between low-voltage logic circuits and high-voltage AC loads.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes include the MOC3010M and MOC3011M, provided the zero-crossing characteristic matches the application needs. Verify that alternative parts maintain the same 4170 Vrms isolation rating and 6-DIP footprint. Check for any differences in trigger current specifications.
