I. overview

Type JK9610A power FET tester is a novel all digital display type power FET parameter test device, can be used for the nominal current of about 2-85A,Test of main parameters of N channel power field effect tube with less than 300W power.It can accurately measure the breakdown voltage VDSS, the gate open voltage VGS (th) and the amplification characteristic parameter transconductance Gfs, especially the transconductance Gfs test current can reach 50A, because the pulse current test method is adopted,Even in high current test, it will not cause any damage to the device under test, and can also test the parameter conformance of the field effect transistor under the condition of large current;The instrument can be used for the measurement of IGBT parameters at the same current level;The instrument is also an electronic component withstanding voltage test device with very good performance,Its test when the leakage current pressure 1mA, 250uA, 25uA, three blocks can be selected.The instrument is mainly used for the quality inspection of power field effect transistors and IGBT, the matching of parameters and the withstanding voltage test of other electronic components.The instrument is divided into two kinds of N channel guide type test instrument and P channel guide type tester. The utility model has the advantages of beautiful appearance, stable performance, accurate measurement, simple operation and convenient and safe use.
