SFH600-1X009T

Overview

The SFH600-1X009T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a gallium arsenide infrared LED emitter optically coupled to a silicon planar phototransistor detector with an accessible base terminal. The device provides high isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum collector-emitter breakdown voltage of 70 V, a maximum forward current of 60 mA, and a typical current transfer ratio ranging from 63% to 125%. The component is housed in a 6-SMD gull-wing package.

Feature Summary

• Integrates a GaAs infrared LED emitter with a silicon planar phototransistor detector for reliable optical signal transmission.
• Provides enhanced safety isolation capabilities through a robust 5300 Vrms insulation voltage rating between input and output circuits.
• Includes an exposed base terminal on the phototransistor to allow for external biasing or improved switching speed control.

Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Microcontroller interface isolation
