MOC3062SR2M

Triac, SCR Output Optoisolators Overview

The MOC3062SR2M is a zero-crossing phototriac driver optocoupler manufactured by Fairchild Semiconductor. It integrates an infrared emitting diode with a monolithic silicon detector that triggers a triac output only when the AC line voltage is near zero crossing. This feature minimizes electrical noise and inrush current during switching. The device provides high isolation between input and output circuits, ensuring safety and signal integrity in power control applications.

Triac, SCR Output Optoisolators Procurement Notes

Verify the manufacturer marking and date code on the component body to confirm authenticity from Fairchild Semiconductor or authorized successors. Ensure the part number suffix matches the specific tape and reel configuration required for your surface mount process. Cross-reference the datasheet revision to confirm compliance with current environmental standards such as RoHS and lead-free specifications before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing functionality is critical to reduce electromagnetic interference in AC power control systems. The surface mount package is suitable for high-volume manufacturing where space constraints exist. Ensure the load voltage does not exceed the peak off-state voltage rating of the integrated triac. Consider thermal management requirements based on the forward current limits of the internal LED driver.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC306X series of zero-crossing optocouplers. It is functionally similar to through-hole variants like the MOC3062M but utilizes a surface mount DIP-6 package. The series is widely used in industrial and consumer electronics for isolating control signals from high-voltage AC loads while minimizing switching transients.

Triac, SCR Output Optoisolators Replacement Considerations

Compatible substitutes include the MOC3061SR2VM and MOC3063SR2VM from the same manufacturer family. These alternatives share identical pinouts and zero-crossing characteristics but differ in peak off-state voltage ratings. Verify that the replacement part's voltage rating meets or exceeds the application requirements before substitution.
