MOC3020SVM

Triac, SCR Output Optoisolators Overview

The MOC3020SVM is a snubberless triac driver optocoupler from onsemi, featuring an infrared LED coupled to a hybrid triac output. It provides electrical isolation for AC power control applications. Key parameters include a 4170Vrms isolation voltage, single channel configuration, and operation within a -40°C to 85°C temperature range. The device utilizes a surface-mount 6-SMD package and accepts DC input with a maximum forward voltage of 1.5V.

Triac, SCR Output Optoisolators Feature Summary

• Snubberless design eliminates the need for external RC snubber networks
• High isolation voltage capability for safety-critical circuits
• Zero-crossing detection minimizes electromagnetic interference

Triac, SCR Output Optoisolators Applications

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

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SVM' confirms the surface-mount package variant distinct from through-hole versions. Confirm RoHS compliance status and check for automotive qualification requirements if applicable to the end application. Ensure supplier documentation matches the official onsemi datasheet specifications.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC loads. The surface-mount format suits automated assembly processes. Compare against other MOC302x series variants based on current handling capabilities and package constraints for the specific PCB layout.

Triac, SCR Output Optoisolators Part Context

Part of the MOC302XM family of snubberless triac drivers. Designed for reliable isolation between low-voltage logic circuits and high-voltage AC mains. Offers improved performance over traditional resistive-triggered optocouplers by integrating zero-crossing detection directly into the hybrid triac structure.

Triac, SCR Output Optoisolators Replacement Considerations

MOC3021SVM: Non-zero-crossing variant for phase-angle control. MOC3023SVM: Higher peak current capability. Verify pinout compatibility and thermal characteristics before substitution.
