MOC3083TVM

Triac, SCR Output Optoisolators Overview

The MOC3083TVM is a single-channel Triac output optocoupler manufactured by onsemi, designed for zero-crossing switching applications. It features an internal photodiode array driving a Triac output capable of handling up to 800 V in the off-state. The device provides high isolation with a rated insulation voltage of 5250 Vrms and supports a maximum forward current of 60 mA. Packaged in a 6-pin PDIP format, it operates within a temperature range of -40°C to +85°C.

Triac, SCR Output Optoisolators Feature Summary

• Integrated zero-crossing detection circuitry minimizes electromagnetic interference during AC load switching.
• High isolation voltage rating ensures safe separation between control and power circuits.
• Internal photodiode array structure enables reliable triggering with low input current requirements.

Triac, SCR Output Optoisolators Applications

• Solid-state relays for AC load control
• Motor speed controllers
• Lighting dimmer circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'TVM' confirms the through-hole PDIP-6 packaging variant. Confirm RoHS compliance status via the manufacturer's latest environmental declaration. Ensure the ordering quantity aligns with tube packaging standards. Cross-reference the datasheet revision date to verify parameter consistency against legacy versions.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing functionality is required to reduce electrical noise in AC switching applications. The 800 V blocking voltage suits standard mains voltage loads. Verify that the 60 mA forward current capability matches the driver circuit design. Consider the PDIP-6 package constraints for PCB layout and thermal management requirements.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3083M series of Triac output optocouplers. It shares functional characteristics with other variants in the family but differs in packaging and trailing zeros. The series is widely used in industrial control systems requiring galvanic isolation for AC power devices.

Triac, SCR Output Optoisolators Replacement Considerations

Direct pin-compatible substitutes include the MOC3081M and MOC3082M, though these lack zero-crossing features. For identical zero-crossing performance, verify equivalent voltage and current ratings in alternative manufacturers' offerings.
