FODM3023R2-NF098

Triac, SCR Output Optoisolators Overview

The FODM3023R2-NF098 is a single-channel triac output optocoupler manufactured by onsemi. It features a gallium arsenide infrared LED coupled to a silicon phototriac, designed for random phase triggering applications. The device provides an isolation voltage of 3750 Vrms and supports a peak repetitive off-state voltage (VDRM) of 400 V. It operates with a forward current of 5 mA and can handle a maximum continuous output current of 70 mA. The unit is housed in a MiniFlat package, suitable for surface mount technology, and functions within a temperature range of -40°C to +100°C.

Triac, SCR Output Optoisolators Feature Summary

• MiniFlat surface mount packaging for compact designs

Triac, SCR Output Optoisolators Applications

• Solid state relays
• AC motor speed control
• Lighting dimmer circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix NF098 against the manufacturer's latest datasheet to confirm tape and reel specifications. Ensure compatibility with standard reflow soldering profiles for the MiniFlat package. Cross-reference the 400V VDRM rating with system requirements to prevent overvoltage stress during operation.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing detection. The 400V blocking voltage suits lower voltage AC mains applications. Consider the 5mA drive current requirement for interface logic compatibility. The MiniFlat form factor is appropriate for high-density PCB layouts requiring robust galvanic isolation.

Triac, SCR Output Optoisolators Part Context

This part belongs to onsemi's family of triac output optocouplers designed for industrial and consumer AC switching. Unlike zero-crossing variants, this model allows immediate triggering regardless of the AC waveform phase. It serves as a critical interface between low-voltage control circuitry and high-voltage AC loads, ensuring safety through electrical isolation.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes include other random phase triac drivers from onsemi such as the FODM3052 series, provided voltage and current ratings are sufficient. Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit.
