FODM2701BR1V

Overview

The FODM2701BR1V is a single-channel transistor output optocoupler manufactured by onsemi. It integrates an aluminum gallium arsenide (AlGaAs) infrared emitting diode with an NPN silicon phototransistor in a compact 4-SMD gull-wing package. The device provides electrical isolation with a rated insulation voltage of 3750 Vrms. Key electrical parameters include a collector-emitter saturation voltage of 300 mV maximum, a forward current of 50 mA maximum, and a collector current of 80 mA maximum. The unit operates within a temperature range of -40°C to +110°C.

Feature Summary

• Integrates an AlGaAs infrared LED with an NPN silicon phototransistor for signal transmission
• Provides high-voltage isolation capability rated at 3750 Vrms between input and output circuits
• Designed for surface-mount assembly using a compact 4-lead gull-wing package

Applications

• General-purpose digital signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic families requiring galvanic separation
• Power supply feedback loops for monitoring and regulation

Procurement Notes

Verify the specific suffix BR1V against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as required by project standards. Check component availability status, as this part may be subject to obsolescence or lifecycle changes. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a small footprint surface-mount optocoupler is required for low-speed digital isolation. The NPN phototransistor output is suitable for standard logic interfacing. Consider the 3750 Vrms isolation rating for safety requirements. Evaluate the 3 µs rise/fall times against system speed needs. Verify that the 4-SMD package aligns with PCB layout constraints.

Part Context

This device belongs to the FODM2701 series from onsemi, which includes various packages such as DIP and SOIC. The series is designed for general-purpose isolation applications. The BR1V suffix typically denotes a specific tape-and-reel packaging configuration for automated assembly. Other variants in the family may offer different pin configurations or lead forms.
