The transistor is one of the most common devices in electronic circuits.
To determine the quality of a transistor, simply check if each PN junction of the transistor is damaged,
The packaging form and pin identification of transistors
Cut off state: When the voltage applied to the emitter junction of the transistor is less than the conduction voltage of the PN junction,
Based on the high or low potential of each electrode during the operation of a transistor
Crystal transistor is one of the basic semiconductor components,
