What are Active components in electronics and Their Classification
Definition of Active components: “Active components are those who has the ability to control flow of electrons either by using voltage or by using another current.” Voltage-controlled devices are MOSFETs, vacuum tubes, while current-controlled devices are bipolar junction transistors which allow one current to control another. Active components can be of different types like semiconductor […]
Shockley Diode Symbol Construction, Working and Applications
You can see Shockley diode symbol it is a four-layer (P-N-P-N) semiconductor device. Like pn junction diode It conducts in forward bias and stops conducting in reverse bias. The main difference between a conventional diode and a Shockley diode is, it starts conducting when the forward voltage crosses its breakdown voltage. It is an active component. It […]
