FOD617BS

Overview

The FOD617BS is a single-channel phototransistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and operates with a maximum forward current of 50 mA and a forward voltage of 1.65 V. The device provides an isolation voltage of 5000 Vrms and supports a collector-emitter voltage of 70 V with a maximum collector current of 50 mA. Key timing parameters include rise and fall times of 18 µs, while the power dissipation is rated at 200 mW. It functions within a temperature range of -55°C to +110°C and is housed in a 4-SMD surface-mount package.

Feature Summary

• Provides galvanic isolation between input and output circuits via an internal LED and phototransistor structure.
• Features a compact surface-mount design suitable for automated assembly processes.
• Offers high insulation voltage capability for safe signal transmission across potential differences.

Applications

• Signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic devices
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'BS' against the manufacturer's official datasheet to confirm pinout orientation and package dimensions, as variations exist within the FOD617 family. Confirm RoHS compliance status through the latest product compliance documentation provided by onsemi before finalizing procurement specifications.

Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation applications. Ensure the circuit design accommodates the specified 18 µs switching speed and 50 mA collector current limits. Verify that the 5000 Vrms isolation rating meets the safety requirements of the target application environment.

Part Context

This part belongs to the FOD617 series of transistor output optocouplers from onsemi. The series is designed for general-purpose isolation tasks, offering a balance of performance and reliability. The BS suffix typically denotes a specific surface-mount package variant within this product line, distinguishing it from through-hole DIP versions.

Replacement Considerations

Compatible substitutes include other single-channel transistor output optocouplers with similar isolation ratings and package types, such as the HCPL-2630 or equivalent generic alternatives, provided electrical parameters match the design requirements.
