Overview
The FODM217BR2V is a single-channel transistor output optocoupler from onsemi, housed in a surface-mount SOP-4 package. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a collector current of 50 mA. The device provides 3750 Vrms insulation voltage and operates within a temperature range of -55°C to +110°C. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.4 V, and a power dissipation of 150 mW. The current transfer ratio ranges from 130% to 260%, with rise and fall times of 3 µs each.
Feature Summary
- Provides high-voltage isolation capability for signal transmission between isolated circuits.
- Utilizes an NPN phototransistor output configuration for standard switching applications.
- Designed for surface-mount assembly to facilitate compact PCB integration.
Applications
- AC/DC sensing input circuits
- General-purpose signal isolation
- Microcontroller interface isolation
Procurement Notes
Verify the specific suffix 'R2V' against the manufacturer's datasheet to confirm packaging details, as this indicates reel or cut-tape availability rather than tube packaging. Ensure the component meets required RoHS compliance standards for the target region. Cross-reference the SOP-4 pinout with the official ECAD model before finalizing layout designs to prevent soldering errors during assembly.
Selection Notes
Select this component when a single channel with moderate speed (3 µs) and high isolation voltage (3750 Vrms) is required. The SOP-4 package suits space-constrained designs compared to larger DIP options. Consider the 130%-260% CTR range for biasing calculations. Verify that the 80 V collector-emitter voltage rating exceeds the load requirements of the application circuit.
Part Context
This part belongs to the FODM217B series of transistor output optocouplers manufactured by onsemi. The series is characterized by its reliability in industrial environments and compatibility with standard surface-mount processes. The FODM217BR2V variant specifically denotes the tape-and-reel or cut-tape packaging format, distinguishing it from tube-packaged equivalents like the FODM217B.
Replacement Considerations
Direct substitutes within the same family include the FODM217B (tube packaging). Other single-channel NPN phototransistor optocouplers with similar isolation ratings may serve as alternatives if pinouts and electrical characteristics align with the design requirements.
