What is a Transistor?

Transistors Functions Transistors have the function of amplifying and switching electrical signals.
Outline of a Transistor This page is a description of the classification of the transistors.
Understanding Transistors In an NPN transistor, the Base is at a positive bias, the Collector at a negative bias, and reverse current flows from the Emitter to the Collector.
What is a Digital Transistor? A digital transistor integrates resistors to efficiently control switching.
Digital Transistor Selection Enter conditions such as current and resistance values, then click on the Calculate button. The result of IC/IB will be displayed, along with recommendations, items requiring confirmation, and areas needing review.
Understanding MOSFET Characteristics This page explains MOSFET Parasitic Capacitance, Temperature Characteristics, Switching time and Temperature Characteristics.
ON Resistance The resistance value between the Drain and Source of a MOSFET during operation is called the ON Resistance.
Total Gate Charge The Total Gate Charge (Qg) is the amount of charge that needs to be injected into the gate electrode to turn ON the MOSFET.
Selecting Transistors to Ensure Safe Operation This section is a description of how to select transistors safely.
Calculating Transistor Chip Temperature The junction temperature rises in proportion to the current consumption. The proportionality constant for this is Rth(j-a).
What is a Load Switch? A load switch is an electronic component that has no moving parts, which works somewhat like a relay.
