Overview
The FODM217BV is a single-channel transistor output optocoupler from onsemi, housed in a compact SOP-4 surface-mount 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 an insulation voltage of 3750 Vrms for robust signal isolation. 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. It operates within a temperature range of -55°C to +110°C.
Feature Summary
- Provides high-voltage isolation between input and output circuits via optical coupling.
- Features fast switching performance suitable for digital signal transmission.
- Designed for AC/DC sensing applications with a single channel configuration.
Applications
- AC/DC sensing input circuits
- Digital signal isolation
- General-purpose optocoupling
Procurement Notes
Verify the specific suffix BV against official datasheets to confirm packaging type and compliance status. Ensure the SOP-4 footprint matches the target PCB design. Confirm RoHS compliance details directly from manufacturer documentation before finalizing procurement specifications.
Selection Notes
Select this component when a single-channel isolation solution with moderate speed is required. The SOP-4 package offers space efficiency for surface-mount assembly. Consider the 130% to 260% current transfer ratio range for circuit gain calculations. Verify thermal management requirements given the 150 mW power dissipation limit.
Part Context
This part belongs to the FODM217B series of transistor output optocouplers manufactured by onsemi. The series includes variants with different current transfer ratios and packaging options. The FODM217BV specifically denotes the tube-packaged version of this standard isolation component.
Replacement Considerations
Check for direct substitutes within the FODM217B family, such as FODM217AV or FODM217CR2V, ensuring pin compatibility and matching electrical characteristics like CTR and isolation voltage.
