FODM3012R4V

Triac, SCR Output Optoisolators Overview

The FODM3012R4V is a single-channel Triac and SCR output optocoupler manufactured by onsemi. It features a PhotoTriac output with no zero-crossing circuit, housed in a 4-pin Miniflat (MFP) surface-mount package. Key electrical parameters include an isolation voltage of 3750 Vrms, a maximum continuous output current of 70 mA, and a blocking voltage (VDRM) of 600 V. The device operates within a temperature range of -40°C to +100°C, with a forward current rating of 60 mA and a power dissipation of 250 mW.

Triac, SCR Output Optoisolators Feature Summary

• Provides galvanic isolation between input control circuits and high-voltage triac loads via an internal LED and photo-triac structure.
• Designed for random-phase triggering applications, allowing conduction at any point in the AC cycle without zero-crossing detection.
• Utilizes a compact 4-pin Miniflow package suitable for automated surface-mount assembly processes.

Triac, SCR Output Optoisolators Applications

• Solid-state relay (SSR) modules requiring random-phase switching capabilities
• AC motor speed control circuits for small appliances
• Lighting dimmer circuits for residential or commercial use

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized onsemi distributors due to obsolete status risks. Confirm package marking and datasheet revision compatibility before integration. Check for alternative sourcing channels as standard inventory may be limited. Ensure storage conditions meet moisture sensitivity level requirements prior to reflow soldering.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triac triggering is required rather than zero-crossing switching. Consider the 600 V blocking voltage and 70 mA output current limits against load requirements. Evaluate the 3750 Vrms isolation rating for safety compliance needs. Compare thermal performance and package size constraints against similar FODM30xx series alternatives.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FODM30xx series of Triac output optocouplers from onsemi. It shares functional similarities with models like the FODM3052R4V but differs in specific electrical ratings and packaging configurations. The series is designed for general-purpose AC power switching applications where electrical isolation is critical.

Triac, SCR Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided documentation. Verify cross-reference data sheets for equivalent random-phase triac optocouplers with matching isolation and current ratings.
