Overview
The FODM217AR2 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 maximum collector current of 50 mA. The device provides an isolation 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 80% to 160%. Switching characteristics specify rise and fall times of 3 µs each. The unit supports an operating temperature range from -55°C to +110°C.
Feature Summary
- Provides galvanic isolation between input and output circuits via optical transmission
- Utilizes an NPN phototransistor for reliable DC sensing applications
- Designed for surface-mount assembly in compact SOP-4 packages
Applications
- DC sensing input circuits
- General purpose signal isolation
- Industrial control systems requiring low-speed switching
Procurement Notes
Verify the specific suffix AR2 confirms the reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your region. Ensure the ordering quantity aligns with standard factory pack sizes to avoid partial reel handling issues during production integration.
Selection Notes
Select this component when a single channel with moderate current transfer ratio is sufficient for isolation needs. The SOP-4 footprint suits space-constrained designs compared to larger DIP packages. Consider the 3 µs switching speed adequate for low-frequency digital signals rather than high-speed data transmission requirements.
Part Context
This part belongs to the FODM217A series of transistor output optocouplers. The series offers various current transfer ratio grades and packaging options including tubes and reels. The FODM217AR2 specifically denotes the version packaged in tape and reel format for efficient surface-mount technology placement.
Replacement Considerations
Compatible substitutes within the same family include FODM217A (tube) and FODM217AR2V. Verify pinout compatibility and electrical parameter equivalence before substitution.
