FODM3023-NF098

Triac, SCR Output Optoisolators Overview

The FODM3023-NF098 is a single-channel triac output optocoupler from onsemi, designed for random phase triac driver applications. It features a Mini-Flat surface-mount package with four pins and provides an isolation voltage of 3750 Vrms. The device supports a maximum continuous output current of 70 mA and a peak off-state voltage (VDRM) of 400 V. It operates within a temperature range of -40°C to +100°C, consumes a maximum power dissipation of 300 mW, and has a typical forward voltage of 1.2 V at a maximum forward current of 60 mA.

Triac, SCR Output Optoisolators Feature Summary

• Random phase triac driver capability without zero-crossing circuitry
• High isolation voltage of 3750 Vrms for safety compliance
• Compact Mini-Flat surface-mount packaging

Triac, SCR Output Optoisolators Applications

• AC motor speed control systems
• Solid state relay drivers
• 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 packaging specifications and pin configuration. Ensure that the 400V rating aligns with the load requirements, as some variants in this family may differ. Cross-reference the RoHS status and material composition declaration for regulatory compliance before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing switching. The 400V blocking voltage suits lower voltage AC loads compared to the 600V rated FODM3052. Consider the Mini-Flat footprint constraints and the 60mA input drive capability relative to the microcontroller or logic interface being used.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FODM302X series of triac output optocouplers. It shares the same physical Mini-Flat package and basic electrical architecture as other members like the FODM3052, but differs in its voltage rating and internal trigger characteristics. The series is designed for industrial and consumer AC power control applications requiring galvanic isolation.

Triac, SCR Output Optoisolators Replacement Considerations

The FODM3052-NF098 serves as a direct functional substitute if the application requires a higher 600V blocking voltage while maintaining the same Mini-Flat package and pinout. Verify that the increased voltage rating does not impact cost or availability constraints.
