FODM3022R1

Triac, SCR Output Optoisolators Overview

The FODM3022R1 is a single-channel optoisolator manufactured by onsemi, featuring a Triac output configuration. It provides an isolation voltage of 3750Vrms between the input and output circuits. The device does not include a zero-crossing detection circuit, allowing for phase-angle control applications. It is housed in a compact 4-SMD surface-mount package and is supplied in Tape & Reel (TR) packaging format.

Triac, SCR Output Optoisolators Feature Summary

• Triac output structure for AC load switching
• High insulation voltage rating of 3750Vrms
• Absence of zero-crossing circuitry for phase control

Triac, SCR Output Optoisolators Applications

• AC motor speed control systems

Triac, SCR Output Optoisolators Procurement Notes

Verify component status as this specific part number is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any replacement strategy accounts for the discontinued status to maintain long-term supply chain stability for existing designs.

Triac, SCR Output Optoisolators Selection Notes

Select this component when phase-angle control of AC loads is required without the timing constraints of zero-crossing switching. The absence of internal zero-crossing logic allows for precise firing angle adjustment. Consider the 3750Vrms isolation capability for safety-critical industrial environments requiring robust galvanic separation.

Triac, SCR Output Optoisolators Part Context

This device belongs to the Triac and SCR Output Optoisolators category from onsemi. It utilizes LED-to-Triac technology to transmit signals across an insulating barrier. The product line supports various power levels and package styles for different thermal and spatial requirements in isolation applications.

Triac, SCR Output Optoisolators Replacement Considerations

As the FODM3022R1 is marked obsolete, identify equivalent Triac output optoisolators with matching 3750Vrms isolation and non-zero-crossing characteristics. Verify pinout compatibility and thermal performance before substitution.
