The commonly used packaging forms of transistors include metal packaging and plastic packaging, and the arrangement of pins follows certain rules, Place the bottom view position so that the three pins form the vertices of an isosceles triangle, with ebc from left to right; For small and medium power plastic transistors, place the plane facing themselves and the three pins facing downwards according to the diagram, and the EBC is from left to right.
Rectifying junctions can also be formed between semiconductors and metals. This type of junction is called Schottky barriers
The basic principle is to use the formed Schottky barrier on the contact surface between metal (such as lead) and semiconductor (N-type silicon wafer) to block reverse voltage
Schottky diode is a common type of diode. It has some unique characteristics that make it widely used in many electronic applications
A Fast Recovery Diode (FRD) is a semiconductor device specifically designed to quickly switch from a conducting state to a cutoff state in a circuit.
After the transistor works in the circuit for a period of time, the circuit components will generate heat (including the heat generated by the transistor itself), and the temperature will continue to rise
