MOC3163SR2VM

Triac, SCR Output Optoisolators Overview

The MOC3163SR2VM is a single-channel Triac and SCR output optocoupler manufactured by onsemi. It integrates an infrared LED with a zero-crossing detection circuit and a photo-Triac, housed in a 6-pin SMD-DIP package. Key electrical parameters include a maximum forward current of 60 mA, a forward voltage of 1.3 V, and a power dissipation of 250 mW. The device supports a peak repetitive off-state voltage of 600 V and provides an isolation voltage of 5250 Vrms. It operates within a temperature range of -40°C to +85°C and features a maximum trigger current of 5 mA.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix SR2VM against official datasheets to confirm surface mount packaging and tape-and-reel delivery format. Ensure compatibility with RoHS directives and check for any recent product change notices regarding pinout or material composition updates from the manufacturer.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize electrical noise in AC load control. Compare the 600 V blocking voltage and 5250 Vrms isolation rating against system requirements. Consider the SMD-DIP footprint for PCB layout constraints and verify thermal management needs based on the 250 mW power dissipation limit.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3163M series of Triac and SCR output optocouplers. It is functionally similar to through-hole variants like the MOC3163VM but utilizes a surface mount package. The series is designed for general-purpose AC power switching applications requiring galvanic isolation between control logic and high-voltage loads.

Triac, SCR Output Optoisolators Replacement Considerations

Cross-reference with MOC3163VM for through-hole equivalents. Verify functional compatibility with other MOC316x series devices if package type differences are acceptable.
