What is Power Transistor? | Definition | Working | Applications: What is Power Transistor? – Power Transistors are now available in ratings suitable for motor control. This device is a 3-layer p-n-p (or n-p-n) structure, as shown in Fig. 11.5. This type of transistor is known as a bipolar junction transistor (BJT). Working: In normal …
What is Silicon Controlled Rectifier (SCR)? | Construction and Working of SCR: What is Silicon Controlled Rectifier (SCR)? – This semiconductor switching device is also known as a thyristor. It is a 4-layer, 3-junction, bistable (ON and OFF) semiconductor switch. The terminal to the outer p-layer is the anode, the terminal to the outer n-layer …
What is Semiconductor Diode?: The Semiconductor Diode (Silicon Rectifier) described here in Fig 11.2(a) are based on the property of p-type and n-type materials in conjunction. An ideal diode presents zero impedance to current flow in one direction and infinite impedance in the opposite direction. A practical diode has a very low forward resistance and …
