A 4N28 optocoupler is a single-channel, industry-standard phototransistor coupler. Instead of the 4N28, optocouplers from the 4N25, 26, 27, and other families are available. Electrically isolated Tx and Rx parts, such as GaAs IR LED and a-Si NPN phototransistor, are included in every optocoupler.

The 2N2646 is a silicon PN Unijunction Transistor that can be used in a variety of industrial applications. The device is commonly used as a triggering device and is not designed to drive high-current loads. This transistor is made out of n-type semiconductors, with the length of the p-type material controlled to help ...
