FODM3052R3V

Triac, SCR Output Optoisolators Overview

The onsemi FODM3052R3V is a single-channel Triac output optoisolator featuring 3750Vrms isolation voltage. It utilizes a random phase Triac capable of handling 600V off-state voltage and 70mA RMS on-state current. The device operates with a maximum forward current of 60mA and typical forward voltage of 1.2V. It supports a minimum static dV/dt of 1kV/µs and functions within a temperature range of -40°C to 100°C. Packaged in a 4-Miniflat surface-mount configuration, it lacks zero-crossing circuitry.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation between control circuits and triac loads via optical coupling.
• Enables direct driving of AC power loads using a random phase Triac output stage without zero-crossing detection.
• Offers robust noise immunity through a minimum static dV/dt rating of 1kV/µs.

Triac, SCR Output Optoisolators Applications

• Solid-state relay (SSR) driver circuits
• AC motor speed control systems
• Industrial process control isolation interfaces

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity carefully as the FODM3052R3V is officially obsolete and no longer manufactured by onsemi. Sourcing should focus on verified surplus stock or approved replacement parts from authorized distributors to ensure reliability and avoid counterfeit risks associated with discontinued semiconductor devices.

Triac, SCR Output Optoisolators Selection Notes

Select this component for applications requiring random-phase triggering of Triacs where precise zero-crossing synchronization is not mandatory. Ensure the design accommodates the 600V blocking capability and 70mA continuous current limits while maintaining adequate creepage distances for the 3750Vrms isolation requirement.

Triac, SCR Output Optoisolators Part Context

This device belongs to the FODM30 series of Triac output optocouplers designed for industrial isolation. It serves as a bridge between low-voltage logic controllers and high-voltage AC power stages, providing galvanic separation to protect sensitive control electronics from electrical noise and transients present in the power domain.

Triac, SCR Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers include FODM3052R4V and FODM3053R3V. These alternatives offer similar Triac output characteristics and isolation ratings but may differ in packaging or specific electrical tolerances; verify datasheet compatibility before integration.
