MOC3083FVM

Triac, SCR Output Optoisolators Overview

The MOC3083FVM is a surface-mount zero-crossing triac driver optocoupler manufactured by onsemi. It integrates an infrared emitting diode with a silicon photo-triac detector to provide electrical isolation for AC power control applications. The device features a 6-lead SMD package and includes an internal zero-crossing circuit to minimize electromagnetic interference during switching. Key electrical specifications include a peak repetitive off-state voltage of 800 V, an isolation voltage rating of 7500 Vrms, and a maximum forward current of 60 mA. It operates within a temperature range of -40°C to +85°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'FVM' against the manufacturer's official datasheet to confirm the exact package dimensions and tape-and-reel specifications. Ensure the procurement source provides valid UL certification documents if safety isolation is required for the end application. Cross-reference the part number with the latest RoHS compliance declarations.

Triac, SCR Output Optoisolators Selection Notes

Select this component when surface-mount assembly is required for zero-crossing triac control circuits. Compare the 800 V blocking voltage and 7500 Vrms isolation rating against system requirements. Consider the thermal dissipation capabilities of the SMD package relative to the ambient operating conditions and duty cycle of the controlled load.

Triac, SCR Output Optoisolators Part Context

This component belongs to the MOC308x series of zero-crossing triac driver optocouplers from onsemi. It is functionally similar to through-hole variants like the MOC3083M but utilizes a surface-mount footprint. The series is widely used in AC power switching applications where low noise generation and galvanic isolation are critical design parameters.

Triac, SCR Output Optoisolators Replacement Considerations

Direct pin-compatible replacements may include other MOC308x series devices such as the MOC3081 or MOC3082, provided the zero-crossing feature and voltage ratings match the design requirements. Verify package compatibility before substitution.
