The KST42 transistor was invented by an American semiconductor company namely “Fairchild Semiconductor International, Inc., located in San Jose, California. This company manufactures different transistors and integrated circuits. So, the KST42 transistor is a high-voltage transistor and it is ideal for lighting, battery charger, and power supply applications. This article gives an overview of the KST42 transistor, pin configuration, specifications, and applications. What is KST42 … [Read more...]

The transistor like PNP operates almost similarly to NPN but the current directions & voltage polarities will be reversed. The flow of current in NPN is from the collector terminal to the emitter whereas in PNP, it is from the emitter terminal to the collector. So, a PNP transistor is generally a type of transistor where n-type material can be doped using two p-type materials. A PNP transistor is an electronic component that is controlled simply through the current supply. So the small … [Read more...]

Transistors that are made completely with metal bodies have been available for quite a long time. The 2N3053 transistor is one of them and is a very popular metal can transistor that is available in the TO-39 package, which is bigger as compared to the TO-18. The transistor has quite interesting characteristics so it is capable of achieving stably in very low & high-temperature conditions. This transistor is mainly designed to utilize in the applications of power oscillators, audio … [Read more...]

PNP transistor is one type of transistor where one n-type material is doped with two p-type materials. This transistor is controlled through the current supply where both the collector & emitter terminals are controlled through the small amount of current at the base terminal. The schematic symbol of this transistor is similar to the NPN transistor but the only difference is the arrow direction on the emitter terminal. In PNP type, the arrow direction is inward whereas in PNP, the arrow … [Read more...]
