FODM3012R2V

Triac, SCR Output Optoisolators Overview

The FODM3012R2V is a single-channel triac output optocoupler from onsemi, designed for random phase triggering applications. It features a gallium arsenide (GaAs) infrared LED coupled to a triac output device within a compact Mini-Flat (MFP) package. The component provides an isolation voltage of 3750 Vrms and supports a maximum continuous on-state RMS current of 70 mA. It operates with a peak repetitive off-state voltage of 400 V and requires a minimum gate trigger current of 5 mA. The device functions reliably across a temperature range of -40°C to 100°C.

Triac, SCR Output Optoisolators Feature Summary

• Random phase triac output suitable for AC power control without zero-crossing detection requirements
• High isolation capability with 3750 Vrms insulation voltage for safety-critical applications
• Compact surface-mount Mini-Flat (MFP) package design for space-constrained PCB layouts

Triac, SCR Output Optoisolators Applications

• Solid state relays for AC load switching
• Motor speed control circuits
• Lighting dimmer modules

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., NF098) against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and pin configuration. Ensure that the selected variant matches the required isolation ratings and thermal performance characteristics for the target application environment before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing switching. Consider the 70 mA RMS current limit and 400 V blocking voltage as primary constraints. Evaluate the Mini-Flat package thermal dissipation capabilities against the expected duty cycle and ambient temperature conditions to ensure reliable operation within the specified -40°C to 100°C range.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FODM30XX series of triac output optocouplers from onsemi. The series is engineered for general-purpose AC power control applications where electrical isolation between low-voltage control circuitry and high-voltage AC loads is necessary. The FODM3012R2V specifically addresses designs requiring robust random phase triggering capabilities in a small form factor.

Triac, SCR Output Optoisolators Replacement Considerations

Cross-reference with other onsemi FODM30XX variants or equivalent triac optocouplers from other manufacturers only if they match the 3750 Vrms isolation, 70 mA RMS current, and Mini-Flat package dimensions. Verify pinout compatibility and trigger current specifications to ensure functional equivalence.
