FOD817DW

Overview

The FOD817DW is a single-channel phototransistor optocoupler from onsemi, featuring a gallium arsenide infrared LED coupled to an NPN silicon phototransistor. It utilizes a wide-body 4-pin DIP (MDIP) package designed for enhanced isolation performance. Key electrical parameters include a maximum collector-emitter voltage of 70V and a peak forward current of 50mA. The device offers a high isolation voltage rating of 5000Vrms. Typical switching characteristics include rise and fall times of approximately 18 microseconds. The unit operates within a temperature range of -55°C to +110°C and complies with UL, CSA, and VDE safety standards.

Feature Summary

Provides galvanic isolation between input control circuits and output load circuits using optical transmission.
Features a wide-body MDIP package structure engineered to support high insulation voltage requirements.
Integrates a gallium arsenide infrared emitter with a silicon phototransistor for reliable signal transfer.
Complies with international safety certification standards including UL, CSA, and VDE.

Applications

Solid-state relay interfaces
Microprocessor system isolation
Signal isolation in industrial control systems

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package dimensions and lead frame material. Ensure the ordering part number matches the required safety certifications such as UL or VDE. Confirm that the wide-body package variant aligns with the PCB footprint and creepage distance requirements of the target design. Cross-reference the revision level to ensure compatibility with existing assembly processes.

Selection Notes

Select this component when high isolation voltage is required in a standard through-hole DIP format. The wide-body construction distinguishes it from standard narrow DIP variants by offering improved dielectric strength. Consider the typical 18-microsecond switching speed for applications not requiring high-frequency data transmission. Verify that the 50mA collector current capability meets the load requirements of the driven circuitry.

Part Context

The FOD817DW belongs to the FOD817 series of general-purpose optocouplers manufactured by onsemi. This series is widely utilized for basic signal isolation tasks. The DW suffix specifically denotes the wide-body dual in-line package configuration. It serves as a robust alternative to narrower packages where higher isolation distances are necessary for safety compliance.
