This document provides technical specifications for the Microsemi UFB, UFS, USB, and USS series of high voltage stackable assemblies. These units utilize only fused-in-glass diodes to ensure reliable operation in bridge or series configurations with controlled avalanche characteristics.
The datasheet details absolute maximum ratings, electrical specifications including forward current recovery times, and mechanical dimensions for each series. It also includes graphical data regarding output current versus air flow velocity and ambient temperature.
| Peak Inverse Voltage (USS Series) | 5.0 kV to 15KV |
|---|---|
| Operating and Storage Temperature Range | -65°C to +150°C |
| Typical Weight (USS & UFS Series) | 1.0 ounce / 28 grams |
| Diode Type | Fused-in-Glass Diodes |
The units operate and store in temperatures ranging from -65°C to +150°C.
A USS or UFS series unit typically weighs 1.0 ounce, which is approximately 28 grams.
Air flow enhances the DC output current, as shown by a factor of 2 in the application example.
