SFH636-X007T

Overview

The SFH636-X007T is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a GaAlAs infrared emitting diode optically coupled to an integrated phototransistor detector. The device provides electrical isolation with a rated insulation voltage of 5300 Vrms. Key electrical parameters include a data rate of 1 Mb/s, a minimum current transfer ratio of 19%, and a maximum forward current of 25 mA. The component supports surface-mount installation in a SMD-6 package and operates within a temperature range of -55°C to +100°C.

Feature Summary

• High-speed signal transmission capability up to 1 Mb/s
• Integrated photodetector for compact design
• High isolation voltage rating for safety
• Wide operating temperature range

Applications

• Industrial communication interfaces
• Signal isolation in control systems
• Data acquisition circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix X007T against official Vishay documentation to confirm the reel packaging configuration and tape-and-reel specifications. Ensure the requested quantity aligns with standard manufacturing pack sizes. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when high-speed digital isolation is required between circuit sections. The 1 Mb/s data rate suits moderate-speed communication protocols. Consider the 5300 Vrms isolation rating for applications demanding robust galvanic separation. Evaluate the SMD-6 footprint constraints during PCB layout. Compare performance metrics against alternative high-speed optocouplers if higher data rates or different output configurations are necessary.

Part Context

The SFH636 series belongs to Vishay's portfolio of high-speed optocouplers designed for reliable signal transmission across isolated boundaries. This specific model utilizes a phototransistor output stage, distinguishing it from logic-output variants like the 6N137 series. The integration of the emitter and detector within a single package ensures consistent optical coupling efficiency and reduces parasitic effects common in discrete designs.
