SFH6747T

Logic Output Optoisolators Overview

The SFH6747T is a high-speed single-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features an infrared LED coupled to an open-drain photodiode output, housed in an 8-SOIC surface-mount package. Key electrical specifications include a data rate of 10 Mb/s, isolation voltage of 3000 Vrms, and common-mode transient immunity of 10 kV/µs. The device operates with a forward current of 20 mA, supports an output current of 50 mA, and functions within a temperature range of -40°C to +100°C. Rise and fall times are specified at 23 ns and 7 ns, respectively.

Logic Output Optoisolators Feature Summary

Logic Output Optoisolators Procurement Notes

Verify component status as the SFH6747T is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure that any replacement components maintain equivalent speed, isolation, and pinout specifications to guarantee system compatibility without redesign.

Logic Output Optoisolators Selection Notes

Select this component when high-speed isolation exceeding standard optocoupler limits is necessary. The 10 kV/µs CMTI rating makes it suitable for environments with rapid voltage transients. Consider the open-drain output configuration for pull-up resistor requirements. Evaluate thermal dissipation capabilities within the SOIC-8 package for continuous operation at elevated temperatures.
