FODM124R2V

Overview

The FODM124R2V is a single-channel phototransistor output optocoupler manufactured by onsemi. It features a compact 4-pin SOP package designed for space-constrained applications requiring DC input isolation. The device provides an isolation voltage of 3750Vrms and supports a maximum forward current of 50mA. Key electrical parameters include a collector-emitter saturation voltage of up to 400mV, a typical rise/fall time of 3µs, and a collector output voltage rating of 80V. The unit operates within a temperature range of -40°C to 110°C and holds VDE certification.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Features a compact surface-mount package suitable for limited board space
• Includes VDE certification for compliance with specific safety standards

Applications

• Space-constrained industrial control systems
• DC input signal isolation interfaces
• General-purpose digital communication isolation

Procurement Notes

Verify the specific ordering suffix R2V to confirm the tape-and-reel packaging configuration required for automated assembly processes. Ensure that the procurement documentation explicitly references the VDE certification status if regulatory compliance is mandatory for the target application environment. Cross-reference the manufacturer part number against authorized distributor lists to guarantee authenticity and traceability of the component batch.

Selection Notes

Select this component when a small footprint is critical alongside standard phototransistor switching speeds. The 3750Vrms isolation rating suits general industrial isolation needs without requiring specialized high-voltage variants. Consider the 400mV saturation voltage for logic level interfacing requirements. Verify that the SOP-4 package dimensions align with the PCB layout constraints before finalizing the design integration.

Part Context

This device belongs to the FODM121 series family from onsemi, sharing similar functional characteristics but distinguished by its specific packaging and certification attributes. The FODM124R2V variant specifically addresses applications needing VDE approval while maintaining the compact form factor of the mini-flat package. It serves as a direct replacement for older through-hole or larger surface-mount optocouplers in modernized designs.

Replacement Considerations

The FODM121AR2V is documented as a parameter-equivalent alternative within the same product family. Both devices share identical channel counts and isolation ratings, though pinout compatibility must be verified during substitution.
