MOC3023TVM

Triac, SCR Output Optoisolators Overview

The MOC3023TVM is a single-channel triac and SCR output optocoupler manufactured by onsemi. It features a photo-triac output without a zero-crossing circuit, designed for random phase control applications. The device utilizes a 6-pin PDIP package with through-hole mounting. Key electrical parameters include an isolation voltage of 5300 Vrms, a maximum forward current of 60 mA, and a peak repetitive off-state voltage (VDRM) of 400 V. The operating temperature range spans from -40°C to +85°C. It is certified under UL and VDE standards.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a photo-triac output stage for direct triggering of triacs and SCRs in AC power circuits.
• Provides high-voltage isolation between input and output sides to ensure safety in mains-connected systems.
• Supports random phase firing capability, allowing conduction angle control at any point in the AC cycle.

Triac, SCR Output Optoisolators Applications

• Solid-state relay designs requiring isolated switching of AC loads.
• Lighting control systems utilizing phase-angle dimming techniques.
• Motor speed control circuits for small AC motors.

Triac, SCR Output Optoisolators Procurement Notes

Verify that the specific suffix 'TVM' corresponds to the tape-and-reel packaging format if automated assembly is required, as opposed to tube packaging found in other variants like MOC3023M. Confirm that the 400 V blocking voltage meets the peak line voltage requirements of the target application. Ensure compliance with RoHS directives and check for automotive qualification status, which is not applicable for this component.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase control is necessary rather than zero-crossing switching. The 400 V rating limits suitability to lower voltage AC lines; higher voltage variants are needed for industrial mains. Consider the 60 mA forward current limit for LED drive circuit design. The PDIP-6 package requires manual or wave soldering processes compared to surface-mount alternatives.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC series of optocouplers from onsemi, specifically engineered for AC power control interfaces. It serves as a bridge between low-voltage digital logic and high-voltage AC power stages. The non-zero-crossing design distinguishes it from MOC3021/3022 series devices, offering flexibility for phase-control applications where precise timing relative to the AC waveform zero-point is not required.

Triac, SCR Output Optoisolators Replacement Considerations

Direct functional substitutes within the same family include MOC3021M and MOC3022M, though these feature zero-crossing detection which alters firing behavior. For identical random-phase operation, verify availability of MOC3023M in alternative packaging formats. Cross-reference pinouts and isolation ratings when considering third-party equivalents to ensure compatibility with existing PCB layouts.
