FODM1007R2V

Overview

The FODM1007R2V is a single-channel transistor output optocoupler manufactured by onsemi. It features an infrared LED coupled to a phototransistor within an LSOP-4 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 70 V and a forward current rating of 50 mA. The device provides 5000 Vrms isolation voltage between input and output. Typical performance metrics include a minimum current transfer ratio of 80% at 5 mA, a maximum collector-emitter saturation voltage of 300 mV, and propagation delays with rise and fall times of 5.7 µs and 8.5 µs respectively. It operates within a temperature range of -40°C to +110°C.

Feature Summary

• Provides high-voltage electrical isolation via an internal infrared LED and phototransistor pair
• Designed for DC sensing applications with a single channel configuration
• Utilizes a compact LSOP-4 surface-mount package for automated assembly

Applications

• DC signal transmission in industrial control systems
• Isolation interfaces for microcontroller peripheral circuits
• Signal coupling in power supply feedback loops

Procurement Notes

Verify the specific suffix R2V corresponds to the required tape-and-reel packaging format when ordering. Confirm that the LSOP-4 footprint matches the target PCB design constraints. Ensure the selected component meets the necessary insulation coordination requirements for the intended application voltage class. Cross-reference the manufacturer datasheet for any recent product change notifications affecting pinout or material composition.

Selection Notes

Select this component when a single-channel isolation barrier is required between low-voltage logic and higher-voltage circuitry. The 5000 Vrms isolation rating supports safety standards for basic insulation applications. Consider the 70 V collector-emitter voltage limit to ensure compatibility with downstream load requirements. The LSOP-4 package offers a space-efficient solution for dense board layouts compared to through-hole alternatives.

Part Context

This part belongs to the FODM100x series of single-channel optocouplers from onsemi. The series is characterized by its use of gallium arsenide infrared LEDs for efficient light emission. These devices are engineered for general-purpose digital signal isolation where moderate speed and high reliability are prioritized over high-speed data transmission capabilities.

Replacement Considerations

Direct replacements must match the LSOP-4 package, 5000 Vrms isolation, and transistor output type. Verify that substitute parts maintain equivalent current transfer ratio and switching speed characteristics to ensure circuit timing integrity without redesign.
