Hello everyone, in this lesson we will learn about the replacement of triodes

2

00:00:05,200 --> 00:00:10,600

When replacing the triode, there are many parameters to pay attention to

3

00:00:11,366 --> 00:00:18,800

But in the PC, the triode is only used as a switch, and the current flowing through it is very small

4

00:00:20,500 --> 00:00:26,233

Therefore, the principle of triode replacement in PC is relatively simple.

5

00:00:26,566 --> 00:00:31,366

It can be replaced only if the package size and structure are the same.

6

00:00:31,900 --> 00:00:40,600

For example, an NPN transistor can be directly replaced by an NPN transistor of the same size.

7

00:00:42,966 --> 00:00:49,200

But if you repair other equipment, the triode cannot be replaced casually,

8

00:00:49,800 --> 00:00:52,533

it is best to replace it with the same model
