Overview
The FODM217AR2V is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and operates within a temperature range of -55°C to +110°C. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a power dissipation of 150 mW. The device provides an insulation voltage of 3750 Vrms with rise and fall times of 3 µs each. The current transfer ratio ranges from 80% to 160%, driven by a forward current of up to 50 mA and a forward voltage of 1.4 V.
Feature Summary
- Provides high-voltage isolation between input and output circuits for signal transmission.
- Utilizes an NPN phototransistor output configuration for digital switching applications.
- Designed for surface-mount installation in compact SOP-4 packages.
Applications
- AC/DC sensing input circuits
- Digital isolation interfaces
- General-purpose signal coupling
Procurement Notes
Verify the specific suffix R2V confirms the reel packaging format required for automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOP-4 package dimensions match the target PCB footprint design constraints. Validate that the 3750 Vrms insulation rating meets the safety requirements of the end application environment.
Selection Notes
Select this component when a single-channel isolation barrier with moderate speed is required. The 80-160% current transfer ratio supports standard logic level interfacing. Consider the -55°C to +110°C operating range for industrial environments. The SOP-4 package offers a compact solution for space-constrained designs compared to larger DIP options.
Part Context
This part belongs to the FODM217A series of transistor output optocouplers. It shares core electrical characteristics with other variants in the family, differing primarily in packaging and current transfer ratio grades. The series is designed for general-purpose isolation tasks requiring reliable performance across wide temperature ranges.
Replacement Considerations
Direct substitutes include FODM217AV and FODM217AR2. Verify pinout compatibility and insulation voltage ratings before substitution. Other series members like FODM217B or FODM217C offer different current transfer ratios but maintain similar package and basic electrical specifications.
