FODM217CR2V

Overview

The FODM217CR2V 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 continuous collector current of 50 mA. The device provides high isolation with an insulation voltage of 3750 Vrms. 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 200% to 400%, with rise and fall times of 3 µs each. It operates within a temperature range of -55°C to +110°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using optical transmission.
• Features an NPN phototransistor output suitable for digital signal switching applications.
• Designed for surface-mount assembly in compact SOP-4 packages.

Applications

• AC/DC sensing input circuits
• Digital signal isolation
• General-purpose switching applications

Procurement Notes

Verify the specific suffix 'R2V' corresponds to the required tape-and-reel packaging configuration, as other suffixes may indicate tube packaging. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure the SOP-4 footprint matches the target PCB layout dimensions exactly. Cross-reference the component marking code with the manufacturer's latest identification guide to prevent counterfeit substitution during procurement.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed (3 µs) and high CTR (200-400%) is required. The SOP-4 package offers a compact form factor compared to traditional DIP options. Consider the 3750 Vrms isolation rating for safety-critical interfaces. Evaluate the 150 mW power dissipation limit against thermal management constraints in dense PCB layouts. Compare against the FODM217AV or FODM217BV if different packaging or CTR grades are needed.

Part Context

This part belongs to the FODM217C series of transistor output optocouplers manufactured by onsemi. The series is characterized by its use in general-purpose isolation tasks where reliable signal transmission across isolated boundaries is necessary. The CR2V designation specifically identifies the surface-mount variant with reel packaging, distinguishing it from through-hole or tube-packaged equivalents within the broader FODM217 family.
