FODM3022R2-NF098

Triac, SCR Output Optoisolators Overview

The FODM3022R2-NF098 is a single-channel triac output optocoupler from onsemi, designed for random phase triac driver applications. It features a peak repetitive off-state voltage of 400V and supports a maximum continuous output current of 10mA. The device provides an isolation voltage of 3750Vrms and operates within a temperature range of -40°C to +100°C. Packaged in a surface-mount Miniflat (SMD/SMT) configuration with four pins, it lacks a zero-crossing circuit, making it suitable for non-synchronized AC power control systems requiring robust electrical isolation.

Triac, SCR Output Optoisolators Feature Summary

• Random phase triac output capability for flexible AC switching
• High insulation voltage ensuring safe signal isolation
• Compact surface-mount packaging for automated assembly

Triac, SCR Output Optoisolators Applications

• AC motor speed control circuits
• Solid state relay drivers
• General purpose AC power switching

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix NF098 against the official onsemi datasheet to confirm package type and tape/reel specifications. Ensure the random phase characteristic aligns with the target application requirements, as this variant does not include zero-crossing detection. Cross-reference the 400V rating with system voltage stresses to maintain adequate safety margins during procurement validation.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing synchronization. The 400V blocking voltage suits low-to-medium voltage AC loads. Consider the Miniflat footprint constraints and thermal dissipation limits relative to the PCB layout. Verify that the 10mA output current capacity meets the gate drive requirements of the downstream triac or SCR being controlled.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FODM30XX series of triac output optocouplers. It shares the same physical Miniflat package and basic isolation architecture as other variants in the family but differs in internal trigger characteristics and voltage ratings. The series is designed for industrial and consumer AC power control applications where compact size and high isolation are prioritized over precise timing synchronization.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes within the same series include FODM3012R2-NF098 and FODM3023R2-NF098. Verify voltage ratings and pin compatibility before substitution. Generic replacements may lack the specific Miniflat footprint or isolation certification.
