SFH636-X007

Overview

The SFH636-X007 is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with a GaAlAs infrared emitting diode optically coupled to an integrated photodetector consisting of a phototransistor. 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%, a forward current of 16 mA, and a forward voltage of 1.5 V. It operates within a temperature range of -55°C to +100°C and is housed in a PDIP-6 Gull Wing package.

Feature Summary

• High-speed signal transmission capability supporting 1 Mb/s data rates
• Integrated photodetector combining optical coupling with transistor output for efficient signal processing
• High isolation voltage ensuring reliable electrical separation between input and output circuits

Applications

• Industrial communication interfaces requiring high-speed data transfer
