FOD617DW

Overview

The FOD617DW is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and is housed in a 4-pin DIP package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum forward current of 50 mA, and an isolation voltage of 5000 Vrms. The device operates within a temperature range of -55°C to +110°C, with typical rise and fall times of 18 µs.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes a standard through-hole DIP package for easy integration
• Features robust insulation capabilities for safety-critical applications

Applications

• General-purpose signal isolation
• Power supply feedback loops
• Industrial control systems

Procurement Notes

Verify the specific suffix 'DW' against the manufacturer's official datasheet to confirm pinout and packaging details. Confirm availability status as distribution channels may list obsolete or discontinued stock. Ensure compliance with RoHS directives if required for the target application environment.

Selection Notes

Select this component when a standard NPN phototransistor output is required for basic isolation tasks. Consider the 5000 Vrms isolation rating for safety compliance. Evaluate the 18 µs switching speed against system timing requirements. Compare thermal dissipation characteristics against the expected operating ambient temperature range.

Part Context

This part belongs to the FOD series of optocouplers from onsemi. It serves as a general-purpose isolation device suitable for replacing older legacy components in existing designs. The DIP-4 form factor ensures compatibility with standard PCB footprints used in industrial and consumer electronics.
