Hey everyone! Hope you all are doing great. Today, I am going to give you the details on the Introduction to 2n4391 . It is a simple N type JFET (Junction field effect transistor) which consists of three terminals called drain, source and gate and are denoted by D, S and G receptively. It is mostly used in analog switches and current limiters. I am going to give you a brief details on this transistor. Let's get started. Introduction to 2n4391 2n4391 is a field effect transistor that consists of three terminals known as drain, source and gate. It is called field effect transistors because static field performs as important part in the operation of this transistor. Unlike normal transistors, it is a voltage controlled device as it doesn't require any biasing current to control large amount o ...
