What is a power transistor? The basic structure, characteristics, working principle, applications, driving protection, installation points, circuit analysis, and development history of power transistors 3

6、 Installation points:

When installing power transistors, the following points should be noted:

1. Temperature control: Power transistors generate significant heat during operation, so some measures need to be taken to control the temperature. You can use heat sinks or heat sinks to dissipate heat and ensure that the temperature of the transistor is not too high.

2. Welding technology: When installing power transistors, welding connections are required. Welding technology needs to be proficiently mastered to ensure that the welding connection is firm and reliable, and will not cause damage to the power transistor.

3. Insulation treatment: Insulation treatment is required between the pins of power transistors and external circuits to prevent current leakage or short circuits. Insulation treatment can be carried out using insulation sleeves or insulation tape.

4. Circuit layout: When installing power transistors, it is necessary to arrange the circuit reasonably to ensure smooth transmission of current and power. To avoid lines that are too long or too short, and to avoid lines crossing or being close to other circuits, in order to reduce interference and losses.

5. Static electricity protection: Before installing power transistors, attention should be paid to preventing the generation and accumulation of static electricity. Static gloves or electrostatic protective pads can be used to reduce the damage of static electricity to power transistors.
