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.
