FODM3012R2-NF098

Triac, SCR Output Optoisolators Overview

The FODM3012R2-NF098 is a single-channel optocoupler featuring a phototriac output, designed for random phase triac driver applications. It operates within a temperature range of -40°C to +100°C and provides an isolation voltage of 3750Vrms. The device supports a maximum continuous output current of 70mA and withstands a off-state output voltage (VDRM) of 600V. Input characteristics include a forward current limit of 60mA and a forward voltage of 1.2V, with a power dissipation rating of 300mW.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a gallium arsenide infrared LED emitter with a sensitive phototriac detector for high-speed switching capabilities.
• Provides robust electrical isolation between input and output circuits without zero-crossing detection logic.
• Constructed in a compact surface-mount MFP package suitable for automated assembly processes.

Triac, SCR Output Optoisolators Applications

• Random phase triac driver circuits
• Solid state relay interfaces
• Industrial control system isolation

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific ordering suffix NF098 to ensure correct tape-and-reel packaging configuration. Confirm that the non-zero-crossing operation aligns with the target application requirements, as this variant differs from zero-crossing models. Check for RoHS compliance status and relevant safety certifications such as UL or VDE before finalizing procurement decisions.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing switching. Ensure the load current does not exceed the 70mA continuous output rating. Verify that the 3750Vrms isolation voltage meets the safety standards of the end equipment. Consider the thermal management requirements given the 300mW power dissipation limit in the small MFP package.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FODM30XX series of triac output optocouplers manufactured by onsemi. It shares functional similarities with other devices in the family but is distinguished by its specific pinout, packaging style, and lack of zero-crossing circuitry. The series is designed for general-purpose AC power control applications requiring galvanic isolation.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other FODM30XX variants with compatible pinouts and electrical ratings. Verify that any replacement maintains the same non-zero-crossing behavior and isolation voltage specifications. Cross-reference mechanical dimensions to ensure fit within the existing PCB footprint.
