SFH636-X001

Overview

The SFH636-X001 is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with a phototransistor output and operates within a temperature range of -55°C to +100°C. The device provides an isolation voltage of 5300 Vrms and supports data rates up to 1 Mb/s. Key electrical parameters include a current transfer ratio of 30% at 16 mA forward current, a maximum forward current of 25 mA, and a forward voltage of 1.5 V. The output can handle up to 8 mA with a saturation voltage of 400 mV. Power dissipation is rated at 100 mW. The component is housed in a 6-DIP package with gull-wing leads.

Feature Summary

• High-speed operation supporting data transmission rates up to 1 Mb/s for efficient signal isolation.
• Robust insulation capability with a rated isolation voltage of 5300 Vrms for safety-critical applications.
• Phototransistor output configuration providing reliable switching performance with defined current transfer characteristics.

Applications

• Industrial control systems requiring high-speed signal isolation
• Communication interfaces needing fast data transmission between isolated domains
• Power supply feedback loops demanding rapid response times

Procurement Notes

Verify the specific suffix designation against official Vishay documentation to ensure correct pinout and electrical specifications. Confirm availability status as distribution channels may list discontinued or end-of-life variants. Cross-reference manufacturer part numbers with authorized distributor catalogs to avoid counterfeit components. Ensure compliance with RoHS directives if required for the target assembly. Validate thermal management requirements based on the specified power dissipation limits during operation.

Selection Notes

Select this component when high-speed digital isolation is required alongside moderate current drive capabilities. The 1 Mb/s data rate suits applications faster than standard logic isolators but slower than dedicated gate drivers. Consider the 6-DIP package for through-hole mounting constraints. Evaluate the 5300 Vrms isolation rating against system safety standards. Compare the phototransistor output type with alternative open-collector or CMOS outputs depending on interface compatibility needs.

Part Context

The SFH636 series belongs to Vishay's portfolio of high-speed optocouplers designed for demanding industrial environments. These devices bridge the gap between standard slow optocouplers and complex digital isolators. The family emphasizes reliability and speed, catering to applications where signal integrity and isolation voltage are paramount. The SFH636-X001 represents a specific variant within this lineage, optimized for transistor-output interfaces.
