SFH6326-X001

Overview

The SFH6326-X001 is a dual-channel high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a GaAlAs infrared emitting diode optically coupled to phototransistor outputs, housed in an 8-DIP package. The device supports data rates up to 1 Mb/s and provides an insulation voltage of 5300 Vrms. Key electrical parameters include a typical current transfer ratio of 35%, a forward current of 16 mA, and a forward voltage of 1.33 V. The unit operates within a temperature range of -55°C to +100°C.

Feature Summary

Dual-channel architecture with GaAlAs infrared LED and phototransistor output
High-speed signal transmission capability at 1 Mb/s
Robust electrical isolation rated at 5300 Vrms

Applications

Industrial communication interfaces requiring galvanic isolation
Data acquisition systems needing high-speed signal transfer
Power supply feedback loops for isolated control signals

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm datasheet revisions match specific lot codes. Check for alternative sourcing options as manufacturing has ceased. Ensure storage conditions comply with moisture sensitivity levels prior to assembly. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Evaluate the 1 Mb/s data rate against system timing requirements. Consider the 35% current transfer ratio for drive circuit design. Assess thermal management needs given the 145 mW power dissipation limit. Verify that the 8-DIP package fits available board space. Compare isolation voltage ratings with safety standards applicable to the target application environment.

Part Context

This component belongs to Vishay's high-speed optocoupler family, designed for applications demanding fast signal propagation and reliable electrical isolation. The SFH6326 series utilizes advanced semiconductor materials to achieve superior performance compared to standard optoisolators. It serves as a critical interface element between low-voltage digital logic and higher voltage industrial circuits.
