SFH6345-X009T

Overview

The SFH6345-X009T is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with a phototransistor output and operates in an SMD-8 package. Key electrical parameters include a data rate of 1 Mb/s, an isolation voltage of 5300 Vrms, and a minimum current transfer ratio (CTR) greater than 30%. The device supports a forward current of 16 mA with a typical forward voltage of 1.33 V. Output specifications include an output current of 8 mA and a power dissipation of 100 mW. Operating temperatures range from -55°C to +100°C.

Feature Summary

High-speed signal transmission capability supporting 1 Mb/s data rates for efficient digital communication.
Robust electrical isolation provided by a 5300 Vrms insulation voltage rating between input and output circuits.
Integrated phototransistor output design ensures reliable switching performance with high current transfer efficiency.

Applications

Industrial automation control systems requiring fast signal isolation
Data communication interfaces needing high-speed galvanic separation
Power supply feedback loops for stable voltage regulation

Procurement Notes

Verify the specific suffix X009T corresponds to the required tape-and-reel packaging configuration rather than tube packaging when sourcing components. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding lead material or assembly processes. Ensure the ordering quantity matches the manufacturer's standard reel size to avoid cut-tape handling issues during assembly.

Selection Notes

Select this component when high-speed digital isolation is critical compared to standard optocouplers. The 1 Mb/s data rate distinguishes it from slower alternatives like the 4N35 series. Consider the SMD-8 footprint for space-constrained PCB designs. Verify that the 5300 Vrms isolation meets system safety requirements and that the CTR >30% specification aligns with the driving circuit capabilities.

Part Context

This part belongs to the SFH6345 family of high-speed optocouplers from Vishay. It utilizes a GaAlAs infrared emitting diode coupled to an integrated photodetector. The family is designed for applications demanding faster response times than general-purpose isolators, offering improved propagation delay characteristics suitable for modern digital protocols.
