SFH636-X009

Overview

The SFH636-X009 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an infrared emitting diode optically coupled to an integrated photo detector comprising a photodiode and a high-speed phototransistor. The device provides electrical isolation with an insulation voltage of 4420 Vrms. Key electrical parameters include a minimum current transfer ratio of 19% at 16 mA forward current, a maximum collector-emitter voltage of 30 V, and a maximum collector current of 50 mA. The unit operates within a temperature range of -55°C to +100°C and is housed in a 6-SMD surface-mount package.

Procurement Notes

Verify the specific suffix X009 against official Vishay documentation to confirm the exact tape-and-reel packaging configuration and quantity per reel. Ensure that the requested component matches the 6-SMD footprint and pinout specifications defined in the datasheet. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability status and lead times prior to order placement.

Selection Notes

Select this component when application requirements demand both high isolation voltage and improved switching characteristics compared to standard phototransistor-only optocouplers. The integrated photodiode allows for faster response times, making it suitable for applications where signal integrity and speed are critical. Evaluate thermal management needs based on the specified power dissipation and operating temperature range.

Part Context

This component belongs to the SFH636 series of optocouplers from Vishay Semiconductor Opto Division. The series is characterized by the integration of a photodiode alongside the phototransistor to enhance performance metrics such as propagation delay and bandwidth. The X009 suffix typically denotes a specific surface-mount packaging variant within this product family.
