Product Summary

The SFH6345 is a 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 in a DIP-8 plastic package. The SFH6345 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. The applications of the SFH6345 include: Data communications, IGBT drivers, Programmable controllers.
