Description
The measuring device for leakage currents LCM 625 is used for measuring the gate leakage currents of MOS-transistors and IGBTs during production (series measurement).
Due to accelerate the measurement the gate capacity (range ≤ 100 nF) is connected to GND by a low-impedance MOS-switch until the test voltage is reached. Then the leakage current is measured.
The leakage current is indicated on a display.
After the measurement has been finished the last measured value is displayed and transferred on request.
The testing voltage is adjustable within a range from 30.0 up to +30.0 V.
The measuring duration covers a range from 100 ms up to 5 s.
An additional display indicates both of the testing parameters.
The measurement can be started manually or via integrated serial interface.
Furthermore a data acquisition software is available for documentation of test lots and statistical evaluation.
