Bridge rectifier boards, high-voltage rectifier stages and diode PCB assemblies are the usual homes for this model, together with the rectifying sections of industrial power supplies and high-voltage equipment that run straight off the mains cycle. On those boards the reverse-voltage path and the clearances around it drive the layout, and where several high voltage diodes sit in one assembly, the spacing at high potential is worked out early. Circuits that draw close to 2 A are the ones this rating is sized for. Where the load is lighter, the higher-voltage steps of the same range fit better; where the current demand is greater, this model is no longer the right choice.
For this part they describe the same ceiling from two angles. Vrrm is the repetitive peak reverse voltage the diode blocks cycle after cycle in normal operation, while Vrwm is the peak working reverse voltage measured under the same test condition. Both are listed as 6 kV at Ta = 25 °C, so the blocking limit is one number rather than a working figure sitting below a higher peak.
Yes. The 50-60 Hz band covers both standard mains frequencies, so the same part serves either supply. For a high voltage diode, the load current and the mounting temperature affect the real margin far more than the few hertz of difference, and the published current ratings are quoted on a 50 Hz half-sine wave.
Short, single events rather than normal running. It is a 0.01 s half-sine pulse at 50 Hz — the shape of stress a rectifier meets when a filter or capacitor bank charges at switch-on, or when the supply is briefly disturbed. It does not add to the 2 A average forward current; the continuous figure stays the limit during steady operation.
The datasheet publishes a forward peak voltage of ≥ 7.2 V for this model, which is the figure to use alongside the 2 A load when estimating conduction loss. The 7 kV and higher steps of the range quote higher limits — 8.5 V and upward — so a 6 kV part gives up less of the design budget to forward drop.
Two: this 6 kV model and the 5 kV one. Above them the range trades current for blocking voltage — 1.5 A from 7 kV to 9 kV, 1.0 A at 10 kV and 11 kV, and 0.8 A from 13 kV to 15 kV. If your circuit's reverse voltage sits comfortably under 6 kV, the 5 kV step gives the same current with a lower ceiling. HVDIODE, one of the high voltage diode manufacturers working in this field, documents each step separately, so the two candidates can be compared on the same terms.
Operating ambient runs from -55 °C to +175 °C. Storage is rated a little narrower, -55 °C to +150 °C, and that figure applies while the part is not passing current. The wide operating window matches the high-temperature die used in this model, so equipment that runs warm stays inside the design window rather than pressing against its edge.
Here, suitable insulation adhesive materials can be selected based on the different usage situations of engineers.
