SFH6316

Overview

The SFH6316 is a high-speed optocoupler featuring a single channel with a data rate of 1 MBd. It consists of a GaAlAs infrared emitting diode optically coupled to a phototransistor output in an 8-SOIC package. Key electrical parameters include a maximum isolation voltage of 4000 Vrms, a typical current transfer ratio of 35% at 16 mA forward current, and a maximum collector current of 8 mA. The device supports a forward voltage of 1.6 V and operates within a temperature range of 0°C to +70°C.

Feature Summary

• High-speed signal transmission capability up to 1 MBd for efficient data isolation
• Integrated GaAlAs infrared LED paired with a phototransistor for reliable optical coupling
• Robust electrical isolation provided by a 4000 Vrms dielectric barrier between input and output circuits

Applications

• Industrial communication interfaces requiring galvanic isolation
• Data acquisition systems needing high-speed signal transfer
• Microcontroller-based control circuits with noise immunity requirements

Procurement Notes

Verify the specific suffix (e.g., T) against the official datasheet to confirm packaging type and reel specifications. Ensure the operating temperature range aligns with system constraints, as standard variants may differ from extended temperature options. Cross-reference pinout diagrams with PCB layout designs to prevent orientation errors during assembly.

Selection Notes

Select this component when a 1 MBd data rate is sufficient for the application's bandwidth needs. Consider the 8-SOIC surface-mount package for automated assembly processes. Evaluate the 35% current transfer ratio to ensure adequate output drive capability for downstream logic or amplifier stages without excessive input current demand.
