タイトルまたは説明

Transistor (transistor) is a solid state semiconductor device (including diode, triode, field effect tube, thyristor, etc., sometimes specifically referring to bipolar devices) with various functions such as detector, rectifier, amplifier, switch, voltage regulator, signal modulation, etc. As a variable current switch, the transistor is able to control the output current based on the voltage. Unlike ordinary mechanical switches (such as Relay, switch), transistors use electrical signals to control their opening and closing, so the switching speed can be very fast, and the switching speed in the laboratory can be over **0GHz
