www.vishay.com SFH6345 Vishay Semiconductors Analog High Speed Coupler, High Noise Immunity, 1 MBd, 15 kV/μs NC 1 A2 C3 NC 4 8 VCC 7 NC 6C 5E DESCRIPTION The SFH6345 is an optocoupler with a GaAlAs infrared emitting diode, optically coupled to an integrated photo detector consisting of a photo diode and a high speed transistor in a DIP-8 plastic package. The 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 2 MHz. This an ideal solution for industrial communication bus isolation, as well as isolated drive circuit applications such as IPM (intelligent power module) drivers.
