After test, please remember to discharge the two terminals of capacitor to avoid electric

Judgment of high voltage silicon stack and high-voltage power transistor‟s BVCEO.
According to the picture below to connect the Withstanding voltage tester with
the tested high-voltage silicon stack or high-voltage power transistor, pay attention to the
DC high-voltage output terminal of the Tester is negative polarity
(-)
, ground wire is
positive polarity
(+)
, and set the leakage current alert value to 0.2mA
,
addvoltage slowly
to the rated value while starting it. If it alerts or the leakage currents augmented, then the
tested high-voltage silicon stack and high-voltage power transistor has been damaged,
contrariwise it is normal.
