FODM3053R2V

Triac, SCR Output Optoisolators Overview

The FODM3053R2V is a Triac and SCR output optocoupler manufactured by onsemi. It features a PhotoTriac output with no zero-crossing circuit, designed for random phase triggering applications. The device provides an isolation voltage of 3750 Vrms and supports a maximum continuous output current of 70 mA. It operates within a temperature range of -40°C to +100°C and utilizes a Miniflat surface-mount package.

Triac, SCR Output Optoisolators Feature Summary

• Random phase triac output capability for precise AC power control
• High isolation voltage rating of 3750 Vrms for safety compliance
• Surface-mount Miniflat packaging for compact board integration

Triac, SCR Output Optoisolators Applications

• Solid-state relay (SSR) driver circuits
• AC motor speed control systems
• Lighting dimmer applications

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix variant required, such as FODM3053R2V-NF098, as availability and status may differ between variants. Some sources indicate limited supply or end-of-life status for certain configurations. Confirm RoHS compliance and material declarations via official onsemi documentation before procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing switching. Ensure the input forward current does not exceed 60 mA and the output current remains within the 70 mA limit. Verify that the 600 V blocking voltage meets the load requirements and that the Miniflat package fits the PCB layout constraints.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FODM30xx series of optocouplers from onsemi. It is functionally similar to parts previously produced under Fairchild Semiconductor branding, reflecting the company's acquisition history. The device serves as a standard interface for isolating low-voltage control logic from high-voltage AC loads in industrial and consumer electronics.

Triac, SCR Output Optoisolators Replacement Considerations

Check for direct substitutes within the FODM30xx family. Verify pinout compatibility and electrical parameters against alternatives like the FODM3052 or FODM306x series if random phase operation is acceptable. Cross-reference datasheets to ensure equivalent isolation and current ratings.
