Shockley diode problem solving

WebA Shockley diode is a four-layer semiconductor diode made from alternating layers of P-type and N-type semiconductor material to form a PNPN structure. It is also known as a four-layer diode or PNPN diode. It has more than one PN junction (actually three PN junctions). If we graph this sequence of events and plot the results on an I/V graph, the hysteresis is evident. First, we will observe the circuit as the DC voltage source (battery) is set to zero voltage: (Figure below) Next, we will steadily increase the DC voltage. Current through the circuit is at or nearly at zero, as the … See more So how can a Shockley diode ever conduct current, if its constituent transistors stubbornly maintain themselves in a state of cutoff? The answer … See more A few special terms apply to Shockley diodes and all other thyristor devices built upon the Shockley diode foundation. First is the term used to … See more
