SFH6345

The SFH6345 is a 1Mbaud 15kV/μs high noise immunity Analogue High Speed Optocoupler with a GaAlAs infrared emitting diode, optically coupled to an integrated photo detector consisting of a photo diode and a high speed transistor. 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 2MHz. It is an ideal solution for industrial communication bus isolation, as well as isolated drive circuit applications such as IPM (intelligent power module) drivers.

• High-speed optocoupler without base connection
• TTL compatible
• Open-collector output
• Good CTR linearity relative to forward current
• Field effect stable
• Low coupling capacitance
