SFH6345

Manufacturer: Vishay

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. Features High speed optocoupler without base connection Integrated detector with photo diode and transistor TTL compatible Open collector output Good CTR linearity relative to forward current Field effect stable Low coupling capacitance Applications Data communications IGBT drivers Programmable controllers Programmable controllers
