SFH6315T

Overview

The SFH6315T is a high-speed optocoupler featuring a single channel with a transistor output that includes a base terminal. It utilizes a GaAlAs infrared emitting diode coupled to a phototransistor, supporting data rates up to 1 MBd. The device provides an isolation voltage of 4000 Vrms and operates within a temperature range of -55°C to 100°C. Packaged in an 8-pin SOIC surface-mount format, it offers robust signal transmission for industrial applications requiring electrical isolation.

Feature Summary

• High-speed data transmission capability up to 1 MBd
• Integrated base terminal on the phototransistor output for enhanced control
• High isolation voltage rating of 4000 Vrms between input and output circuits
• Wide operating temperature range suitable for demanding environments

Applications

• Industrial automation systems requiring fast signal isolation
• Power supply feedback loops for isolated control signals
• Data communication interfaces needing galvanic isolation
• Microcontroller input/output isolation in noisy environments

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Vishay Semiconductor Opto Division to ensure component authenticity. Check RoHS compliance status against current regulatory requirements for your region. Ensure the procurement source provides valid datasheets matching the SFH6315T part number for technical reference.

Selection Notes

Select this component when a high-speed response time is critical for signal integrity. The integrated base allows for faster switching speeds compared to standard phototransistors. Consider the 8-pin SOIC package for space-constrained PCB layouts. Verify that the 4000 Vrms isolation meets the safety standards required by your application's electrical design specifications.

Part Context

This component belongs to the SFH63xxT series of high-speed optocouplers from Vishay. These devices are designed for applications demanding rapid signal transfer across isolation barriers. The series typically includes variants like the SFH6316T, which shares similar architectural features but may differ in specific electrical characteristics or pin configurations.

Replacement Considerations

The SFH6316T is a related high-speed optocoupler within the same product family. Verify compatibility regarding pinout and electrical parameters before substitution. Ensure that any replacement maintains the required 1 MBd data rate and isolation voltage levels for the specific circuit design.
