SFH6345-X017T

The SFH6345-X017T from Vishay is a high noise immunity, 1MBd, 15KV/μs, analogue high speed coupler in 8 pin surface mount DIP package. This optocoupler with a GaAlAs infrared emitting diode optically coupled to an integrated photo detector consisting of a photo diode and a high speed transistor. Device is similar to the 6N135 but has an additional faraday shield on the detector which enhances the input-output dV/dt immunity. Signals can be transmitted between two electrically separated circuits up to frequencies of 2MHz. This an ideal solution for industrial communication bus isolation as well as isolated drive circuit applications such as IPM (intelligent power module) drivers. It is used in IGBT drivers, programmable controllers and IPM (intelligent power module) drivers.
