Basic knowledge of crystal SMD diode

1. What types of diode do you know?

    Switching diode (small signal diode), Schottky diode, rectifier diode, Zener diode (Zener diode), transient voltage suppression diode (TVS), varactor diode, light emitting diode (LED).

2. What is the working principle of TVS transient voltage suppression diode?

    When the voltage on the TVS exceeds a certain amplitude, the device is quickly turned on, thereby discharging the surge energy, so that the surge voltage is limited to a certain amplitude.

3. What SMD diode models do you know?

    1N4148, 1N5817, 1N5819, 1N5820, 1N5822, 1N4001, 1N4007, SR160, SR360, BAT54A, BAT54C, BAT54S

4. What are the models of NPN type SMD transistors you know?

    2N2222, 2N3904, 2N5550, 2N5551, M8050, S9013, S9014, S9018

5. What PNP patch transistor models do you know?

    2N3906, M8550, S9012, 2SB1005, 2SB1184, 2SB1386, 2SB1412, 2N4403, 2N4030

6. What P-MOS tube model do you know?

    AO3415, Si2301DS, Si2305DS, AP4435M, AP9435M
