SFH6345-X019T

Overview

The SFH6345-X019T is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with a phototransistor output, housed in an SMD-8 package. The device supports data rates up to 1 Mb/s and provides an insulation voltage of 5300 Vrms. Key electrical parameters include a forward current of 16 mA, forward voltage of 1.33 V, reverse voltage of 3 V, output current of 8 mA, and power dissipation of 100 mW. The current transfer ratio exceeds 30%. Operating temperatures range from -55°C to +100°C.

Feature Summary

High-speed operation supporting data transmission rates up to 1 Mb/s
Integrated phototransistor output for signal isolation
Robust insulation capability with 5300 Vrms isolation voltage

Applications

Industrial communication interfaces requiring galvanic isolation
Signal isolation in microprocessor-based control systems
Power supply feedback loops in switching regulators

Procurement Notes

Verify the specific suffix X019T corresponds to the SMD-8 surface mount package variant, as other suffixes may indicate PDIP through-hole packages. Confirm RoHS compliance status and check for any recent PCN updates regarding design or assembly changes. Ensure the supplier provides official datasheets matching the exact part number to avoid confusion with similar high-speed optocoupler models.

Selection Notes

Select this component when high-speed digital isolation is required in compact surface-mount designs. The 1 Mb/s data rate suits moderate-speed serial communications. Consider the 5300 Vrms isolation rating for applications demanding strong safety barriers. Evaluate the 16 mA forward current requirement against available drive capabilities. Compare against alternative Vishay series if different packaging or speed characteristics are needed.

Part Context

This part belongs to the SFH6345 series of high-speed optocouplers from Vishay. The series includes various package options such as PDIP and SMD configurations. The SFH6345-X019T specifically denotes the surface-mount version optimized for automated assembly processes while maintaining the high-speed performance characteristics of the broader family.
