HSD-Series Axial Lead SiC High Voltage Diodes
View productThe PD5 series SMD high voltage diodes are a surface-mount rectifier family rated up to 5 kV, built with a gullwing SMD package that keeps one board footprint across current ratings. Each 5KV SMD high voltage diode uses high thermal conductivity epoxy molding and a fast recovery design for high-speed switching circuits.
The PD5 series is a surface-mount high voltage rectifier family. Each device uses SMD connection with gullwing (outer bend) shapes, and the whole series is made in the same ultra-small package size, so a board laid out around one current rating can be re-populated with another model without changing the footprint.
High thermal conductivity epoxy compound molding carries heat away from the junction, while the fast recovery design keeps switching losses low in high-speed circuits and supports efficient energy conversion.
Ultra-low power consumption design is intended to improve rectifier circuit conversion efficiency, and the series is described as performing well in high temperature environments with consistent performance under extended operation.
Fourteen current variants are published, from PD5A at 20 mA to PD5N at 500 mA. All of them carry a 5 KV repetitive reverse voltage rating and a 10 A forward surge current rating, with reverse leakage listed as 1 / 20 µA (Irrm1 / Irrm2). Forward voltage drop rises with the current rating, from 4.1 V on PD5A to 6.2 V on PD5N.
Recovery time splits into two groups: 70 nS for PD5A through PD5F, and 75 nS for PD5G through PD5N.

Because the package is shared, the choice between models comes down to rated current and the resulting forward drop. The steps below follow the published table.
Every published PD5 model is listed at Vrrm 5 KV, so the reverse voltage requirement is fixed across the series.
Choose from 20 mA on PD5A, stepping through 30, 50, 60, 80, 100, 150, 200, 250, 300, 350, 400 and 450 mA, up to 500 mA on PD5N.
Vfm runs from 4.1 V on PD5A to 6.2 V on PD5N, so higher-current models carry a larger forward drop in the circuit.
PD5A to PD5F are listed at 70 nS; PD5G to PD5N are listed at 75 nS. Pick the group that fits the switching speed of the stage.
Ifsm is 10 A across the range, with reverse leakage of 1 / 20 µA (Irrm1 / Irrm2) for every model.
For parameter requirements beyond the published list, contact customer service at sales@hvdiode.com.
The published application list covers medical, power supply, appliance, instrument, industrial, automotive and new energy equipment.
Listed applications include X-ray machines, CT machines and nuclear magnetic resonance systems.
Switching power supplies, inverter power supplies and power supply filter circuits.
TVs, refrigerators and washing machines are named among the application areas.
Instrumentation and radar equipment appear on the published application list.
High-precision current regulation and voltage stability in industrial control circuits.
Charging systems and EV drive systems, plus solar panels and wind turbines for new energy equipment.
Before a PD5 model goes onto a board, it is worth confirming the part against the published record rather than relying on a single line of the catalogue.
Because all fast recovery PD5 series parts share one package size, a verified footprint can be reused if the current rating later changes.
Tell us the model or the current rating you need, the circuit it goes into and the quantity, and our team will confirm availability. If your requirement falls outside the published 5 KV, 20–500 mA, 70–75 nS range, customer service can review it at sales@hvdiode.com.
Every published pd5 model is listed at vrrm 5 kv, from pd5a through pd5n.
Fourteen models are listed, starting at 20 ma on pd5a and rising through 30, 50, 60, 80, 100, 150, 200, 250, 300, 350, 400 and 450 ma to 500 ma on pd5n.
Pd5a through pd5f are listed at 70 ns, and pd5g through pd5n at 75 ns.
Ifsm is listed at 10 a for all fourteen pd5 models, with reverse leakage of 1 / 20 µa (irrm1 / irrm2).
They use smd connection with gullwing (outer bend) shapes in an ultra-small package, and the fast recovery pd5 series parts share the same package size.
