Witryna19 mar 2024 · A Silicon-Controlled Rectifier, or SCR, is essentially a Shockley diode with an extra terminal added. This extra terminal is called the gate, and it is used to trigger the device into conduction (latch it) by the application of a small voltage. WitrynaShockley diode definition is; a semiconductor switching diode which includes four layers like P-N-P-N and two terminals like anode & cathode and this diode is also called the PNPN diode or four-layer diode. Shockley Diode. The function of this diode is similar to a normal diode exclusive of any trigger inputs.
