Overview
The SFH636 is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with a phototransistor output and operates in a PDIP-6 Gull Wing package. The device supports data rates up to 1 Mb/s and provides an insulation voltage of 5300 Vrms. Key electrical parameters include a current transfer ratio of 30% at 16 mA forward current, a maximum output current of 8 mA, and a power dissipation of 100 mW. It functions within a temperature range of -55°C to +100°C.
Feature Summary
- High-speed operation capability for digital signal transmission
- Integrated phototransistor output stage
- High isolation voltage rating for safety applications
Applications
- Industrial communication interfaces
- Data acquisition systems
- Power supply feedback loops
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific suffix variations against the official datasheet. Check for end-of-life notifications as availability may be restricted. Ensure packaging type matches design requirements before ordering.
Selection Notes
Select this component when high-speed digital isolation is required in a compact DIP package. Evaluate the 1 Mb/s data rate against system timing constraints. Consider the 5300 Vrms isolation barrier for safety-critical designs. Verify thermal management needs given the 100 mW power dissipation limit.
Part Context
The SFH636 belongs to Vishay's high-speed optocoupler family, designed for robust signal transmission across isolated boundaries. It utilizes a GaAlAs infrared emitting diode coupled to an integrated photodetector. This series is engineered for applications demanding fast switching speeds and reliable electrical isolation in industrial and commercial environments.
Replacement Considerations
Cross-reference with SFH636-X007T or SFH636-X001 for alternative packaging or specification variants. Verify pinout compatibility and electrical parameter alignment before substitution.
