WebPN Junction diode is a device made of two semiconductor material joined together with the required amount of impurity. These materials are N-type, having electrons are majority carrier and P-type material, having holes are majority carrier. With proper biasing, PN diode allows current to flow in SINGLE DIRECTION. WebNow, for an open-circuited (i.e., disconnected) junction diode, the total current through the device must be zero. In other words, the diffusion current I D must be equal but opposite that of the drift current I S, such that: I D – I S =0 This is the equilibrium state of a disconnected junction diode.
