Vishay SFH6345 High Speed Optocoupler
The SFH6345 is a high-speed, high noise immunity optocoupler with a baud rate of 1 Mbaud and a voltage rating of 15 kV/μs. It features a GaAlAs infrared emitting diode optically coupled to an integrated photodetector composed of a photodiode and a high-speed transistor. The device includes an additional Faraday shield on the detector to improve input-output dV/dt immunity. Capable of transmitting signals between two electrically isolated circuits at frequencies up to 2 MHz, it is ideal for industrial communication bus isolation and isolated drive circuits such as intelligent power module (IPM) drivers. The optocoupler is TTL compatible, has an open-collector output, and exhibits good current transfer ratio (CTR) linearity relative to forward current, with stable field effect operation and low coupling capacitance.
