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.
