FOD617C300W

Overview

The FOD617C300W is a single-channel phototransistor output optocoupler manufactured by onsemi. It features a 4-pin MDIP package designed for through-hole mounting. The device provides an isolation voltage of 5000Vrms, ensuring robust electrical separation between input and output circuits. It operates with a DC input type and supports a maximum forward current of 50mA. The unit functions within a temperature range of -55°C to +110°C. Key electrical parameters include a collector-emitter saturation voltage of 200mV and a power dissipation rating of 200mW. The component is part of the FOD series and holds UL and VDE certifications.

Feature Summary

• Provides high-voltage galvanic isolation via a phototransistor output architecture
• Designed for reliable operation across extended industrial temperature ranges
• Features a standard four-lead molded DIP package for easy integration

Applications

• General-purpose signal isolation in electronic circuits
• Power supply feedback loops for voltage regulation
• Solid-state relay driver interfaces

Procurement Notes

Verify the specific suffix 'W' against the manufacturer's official datasheet to confirm pinout orientation and packaging specifications. Ensure that the required isolation voltage ratings align with your system's safety standards. Cross-reference the exact part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a standard phototransistor output is sufficient for the application logic levels. Consider the 50mA collector current limit when designing load resistors. Evaluate the thermal management requirements given the 200mW power dissipation constraint. Compare propagation delays if high-speed switching is required, as this device is optimized for general-purpose rather than high-frequency applications.

Part Context

This component belongs to the FOD series of optocouplers from onsemi. The series is widely recognized for providing cost-effective isolation solutions in various industrial and consumer electronics. The FOD617 variant specifically utilizes a phototransistor output, distinguishing it from transistor-array or logic-output alternatives within the broader product family.
