SFH617A-1XG

Overview

The SFH617A-1XG is a single-channel optocoupler featuring an infrared emitting diode and an NPN silicon phototransistor. It utilizes a 4-pin DIP package for through-hole mounting. Key electrical parameters include a maximum collector-emitter voltage of 80V, a peak forward current of 60mA, and a typical forward voltage of 1.65V. The device provides an isolation voltage of 4470Vrms with a rise time of 4.6µs and a fall time of 15µs. Power dissipation is rated at 200mW, operating within a temperature range of -55°C to +110°C.

Feature Summary

Integrates an infrared LED with an NPN silicon phototransistor for signal transmission
Provides high-voltage electrical isolation between input and output circuits
Designed for through-hole mounting in standard 4-pin DIP configurations

Applications

General-purpose signal isolation in electronic circuits
Interface between microprocessors and high-voltage loads
Switching applications requiring galvanic isolation

Procurement Notes

Verify the specific manufacturer designation when sourcing, as Isocom Components may distribute components originally manufactured by other semiconductor vendors such as Vishay. Confirm that the datasheet specifications align with your design requirements, particularly regarding the isolation voltage rating and thermal characteristics. Ensure the package type matches your PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring robust galvanic isolation with moderate switching speeds. The NPN phototransistor output is suitable for standard logic interfacing. Consider the 80V collector-emitter voltage limit when designing for higher voltage loads. The wide operating temperature range supports use in industrial environments where thermal stability is critical for reliable signal transmission.

Part Context

This part belongs to the family of transistor-output optocouplers designed for general isolation purposes. It shares functional similarities with other industry-standard devices like the SFH617A series variants. The component serves as a fundamental building block for creating electrically isolated communication paths or power control interfaces in various electronic systems.
