1. Regarding the above, how do you know the diode model? Regarding this question, please refer to the following information for details. I hope it will be helpful to you: Take the 2CP10 diode as an example. The "2" of this diode represents the diode. "C" represents the N-type silicon material. "p" represents that it is an ordinary tube. "10" ” indicates its serial number. Through reading, it can be seen that the two limits are N-type ordinary silicon material diodes. For reference only!
