FODM3052R1_NF098

Triac, SCR Output Optoisolators Overview

The FODM3052R1_NF098 is a Triac and SCR output optocoupler manufactured by onsemi. It features a single channel with a PhotoTriac output type and operates without a zero-crossing circuit, classifying it as a random phase device. The component provides an insulation voltage of 3750 Vrms and supports a maximum continuous output current of 70 mA. It is designed for surface mount installation in a Miniflat (4-SMD, Gull Wing) package. The device handles a forward current of up to 60 mA with a forward voltage of 1.2 V and dissipates power up to 300 mW. It functions within a temperature range of -40°C to +100°C and blocks voltages up to 600 V in the off state.

Triac, SCR Output Optoisolators Feature Summary

• Random phase triac driver capability for precise AC power control applications
• High isolation voltage rating ensuring safe separation between input and output circuits
• Compact surface-mount Miniflat packaging suitable for space-constrained designs

Triac, SCR Output Optoisolators Applications

• Solid-state relay systems requiring random phase triggering
• AC motor speed control circuits
• Lighting dimmer modules

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix NF098 against official datasheets to confirm tape and reel packaging details. Confirm that the part status is obsolete before finalizing procurement plans. Ensure compatibility with existing PCB footprints for the 4-SMD Miniflat package. Cross-reference manufacturer documentation for any recent lifecycle announcements or recommended replacements.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triac driving is required rather than zero-crossing switching. Verify that the 600 V blocking voltage meets the peak line voltage requirements of the application. Ensure the 70 mA output current capacity is sufficient for the gate drive needs of the target triac or SCR. Check that the operating temperature range aligns with the environmental conditions of the end product.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FODM3052 series of optoisolators from onsemi. It is functionally similar to other variants like the FODM3052-NF098 but may differ in packaging format such as tube versus tape and reel. The series is designed for industrial and consumer AC power control applications where electrical isolation is critical.

Triac, SCR Output Optoisolators Replacement Considerations

Public sources indicate the FODM3052R1_NF098 is obsolete. Potential substitutes include other random phase triac output optocouplers from onsemi or competitors with matching 3750 Vrms isolation and Miniflat packages. Verify pinout compatibility and electrical parameters before substitution.
