MOC3083TM

Triac, SCR Output Optoisolators Overview

The MOC3083TM is a zero-crossing triac output optocoupler manufactured by onsemi. It features a single channel with a PhotoTriac output and an integrated zero-crossing detection circuit for low EMI switching. The device provides high isolation voltage of 4170 Vrms and supports a peak repetitive off-state voltage of 800 V. It operates within a temperature range of -40°C to 85°C and is housed in a 6-DIP package.

Triac, SCR Output Optoisolators Feature Summary

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'TM' against official onsemi documentation, as standard listings often use 'M' or 'VM'. Confirm package type and isolation ratings match design requirements. Check RoHS compliance status and lead times with authorized distributors. Ensure the component is sourced from verified channels to avoid counterfeits.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise. Compare isolation voltage ratings against system safety standards. Consider the 800V blocking voltage for appropriate AC line applications. Verify thermal management needs within the specified operating temperature range.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC308x series of zero-crossing triac output optocouplers. It shares functional similarities with MOC3081, MOC3082, and MOC3083 variants, differing primarily in packaging and specific rating configurations. The series is widely used in industrial AC control systems requiring galvanic isolation.

Triac, SCR Output Optoisolators Replacement Considerations

MOC3083M and MOC3083VM are functionally equivalent alternatives within the same family. Verify pinout compatibility and isolation voltage ratings before substitution. Ensure the replacement part meets the same zero-crossing timing specifications.
