The quality and match of switching transistor affects the quality and reliability of electronic ballast. Too big saturation voltage of the switching transistor will cause too much heat and affects the normal work of EB. If the paired switching transistors have too big difference in Ts and hFE, the EB work in non-symmetric state to induce the heat-up of elements, and even destroy switching transistor. KF-2 is designed for this requirement with intuitional display and fast classification function, so it is the best choice for the manufacturers of EB and transistor to classify switching transistor quickly.
