The SourceMeter instrument first performs the necessary DC tests, such as forward voltage, reverse breakdown voltage, and leakage current.
The response time is very important in determining the breakdown voltage.
The exact determination of the breakdown voltage must therefore be attached to the measurement of an electrical value characteristic of the dielectric breakdown phenomenon.
As shown in Diagram 1, as from the voltage Uc, the leakage current increases very swiftly and the breakdown voltage is reached for value ue.
The breakdown voltage of the single air-gap discharge was lower than that of the double airgap discharge.
In the in- active state, the breakdown voltage were higher than the single air in the same conditions under AC and positive DC voltage, but it was opposite under negative DC voltage.
The base current and the junction leakage current increase, while the collector current and the breakdown voltage decrease for SiGe HBTs after radiation.
