MOC3020FVM

Triac, SCR Output Optoisolators Overview

The MOC3020FVM is a single-channel triac output optocoupler manufactured by onsemi. It features a non-zero-crossing photo-triac designed for driving AC loads such as heaters, lamps, and solenoids. The device provides high isolation voltage of 7500 Vrms between the input LED and output triac. It operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum forward current of 60 mA, a peak repetitive off-state voltage of 400 V, and a maximum gate trigger current of 30 mA. The component is housed in a 6-lead surface-mount package.

Triac, SCR Output Optoisolators Feature Summary

• Non-zero-crossing switching capability allows for phase-angle control applications
• High isolation voltage ensures safe separation between control and power circuits
• Integrated photo-triac output simplifies interface with AC load drivers

Triac, SCR Output Optoisolators Applications

• Solid state relay (SSR) modules
• AC motor speed control circuits
• Heater and lamp dimming systems

Triac, SCR Output Optoisolators Procurement Notes

Verify that the specific suffix 'FVM' corresponds to the required surface-mount packaging and tape-and-reel configuration. Confirm that the 7500 Vrms isolation rating meets the safety requirements of the target application. Ensure compatibility with the non-zero-crossing switching characteristic for phase-control designs.

Triac, SCR Output Optoisolators Selection Notes

Select this component when phase-angle control is required rather than zero-crossing switching. The surface-mount package suits automated assembly processes. Consider the 400 V blocking voltage limit for low-voltage AC applications. Verify thermal management requirements for the SMD package in high-power environments.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC302XM series of triac output optocouplers. It shares functional similarities with through-hole variants like the MOC3020M but utilizes a surface-mount footprint. The series is widely used in industrial control and consumer appliance applications requiring galvanic isolation for AC switching.

Triac, SCR Output Optoisolators Replacement Considerations

Direct pin-compatible replacements may include other MOC302X series devices from onsemi or equivalent triac output optocouplers from manufacturers such as Vishay or Everlight, provided they match the 7500 Vrms isolation and non-zero-crossing characteristics.
