Replacement usually starts with the number marked on the old diode. The HVRM range steps from 5 kV to 15 kV, and this model sits in the 0.8 A current tier alongside the 13 kV and 15 kV versions, so a design can move one step up or down in voltage without leaving the same current class. Order by the marked part number, then confirm two things before you commit: the peak reverse voltage your circuit can actually produce, including transients, and the lead form and footprint on the board, because the right rating in the wrong footprint still will not drop in. Every rating comes off our own line, so changing voltage does not mean changing high voltage diode manufacturers or re-qualifying a new process.
Selection support starts before you order. Our technical team reviews your working voltage, forward current, surge and thermal conditions against the published datasheets, then recommends the closest high-voltage diode and confirms the matching part number. We also guide you through installation and insulation considerations, and help troubleshoot issues during qualification or after delivery. Suly Electronics manufactures these diodes directly, supplies them in bulk, and keeps answering technical questions for the parts you already use.
No. It is built for low-frequency rectification, and no reverse recovery time is published for it. If your circuit switches in the kilohertz range, choose one of our fast recovery diodes instead; for mains-frequency rectifier stages this part is the correct type.
Vrrm is the repetitive peak reverse voltage the diode blocks in normal, repeated operation. Vrwm is the peak working reverse voltage under the same condition. Both are 14 kV on this model, so the figure you plan around for continuous rectification is the same one quoted for working voltage.
At rated reverse voltage, leakage is 2.0 µA at 25 °C and rises to 20.0 µA at 100 °C. That rise is normal for a diode in this class, but it matters in high-impedance circuits, so check the leakage budget wherever a small reverse current cannot be tolerated.
It is the peak forward voltage across the diode under its rated forward condition. A 14 kV device has to hold off far more voltage than a low-voltage rectifier, and that capability shows up as a higher forward drop, which becomes heat while current flows. Check the figure against your loss budget before finalizing the design.
Keep them in the original packaging in a dry store and within the storage temperature range shown on the data sheet. Leave the pack sealed until the parts are needed, and handle the leads carefully so they stay straight for the assembly line.
Treat them like any axial through-hole semiconductor. Support the lead where it leaves the body, make the bend away from the seal, and keep soldering heat brief. The cured epoxy body itself is robust; the lead-to-body seal is the part worth protecting.
Here, suitable insulation adhesive materials can be selected based on the different usage situations of engineers.
