We often encounter customers saying that some vendors have bought high-voltage diodes and they can’t use them. After communication, they will know that the customer only asked about the voltage of the high-voltage diodes, and the vendors only care about the voltage, the current is only 5mA, and the customer needs It’s 100mA. It’s only strange if it can be used. It’s caused by the unprofessional sales staff. If you are professional, you must at least ask about the current and frequency required by the customer; some customers say that it is the same high voltage as us, why are you so so? Expensive, after understanding the current difference, even the volume will be different when the current is large.

Some manufacturers of high-voltage diodes directly mark the model number on the tube body, some are marked with a code number, and some are directly indicated by a negative graphic. First of all, you need to determine the high voltage diode parameters you need (including: voltage, current, frequency, leakage current, etc.). Of course, it is convenient to know the model and manufacturer. If there is no model, remember to confirm the main with the manufacturer or seller. Parameters, they are required to provide physical pictures and electronic document PDFs. Generally, PDFs have a negative mark or code number, which is generally not wrong, and can avoid buying inappropriate back and forth.
