FOD617C300

Overview

The FOD617C300 is a single-channel phototransistor output optocoupler manufactured by onsemi. It provides electrical isolation with a rated isolation voltage of 5000 Vrms. The device features an NPN phototransistor output capable of handling a maximum collector current of 50 mA and a collector-emitter voltage of 70 V. It operates within a temperature range of -55°C to +110°C. The component is housed in a 4-pin PDIP Gull Wing surface-mount package.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes an NPN phototransistor for signal transmission
• Designed for surface-mount installation via gull-wing leads

Applications

• General-purpose signal isolation in electronic circuits
• Interface applications requiring galvanic separation
• Industrial control systems utilizing transistor outputs

Procurement Notes

Verify the active status of this part number, as official documentation indicates it may be obsolete or no longer manufactured. Confirm availability through authorized distributors or identify approved substitute components if production supply is restricted. Ensure the specific package variant matches design requirements before ordering.

Selection Notes

Select this component for applications requiring standard-speed transistor output isolation in a surface-mount form factor. Consider the 5000 Vrms isolation rating for safety compliance. Evaluate thermal management needs given the operating temperature range up to 110°C. Verify that the 50 mA output current capability meets the load requirements of the downstream circuitry.

Part Context

This component belongs to the FOD series of optocouplers from onsemi, designed for general-purpose isolation tasks. It shares functional similarities with other transistor-output isolators but is distinguished by its specific surface-mount packaging and voltage ratings within the manufacturer's portfolio.

Replacement Considerations

Official sources list FOD817C300 as a similar available substitute. Verify pinout compatibility and parameter equivalence before replacement.
