With the increasing use of power devices fabricated from emerging new materials such as SiC and GaN, switching power supplies are operating at increasingly higher frequencies. This makes accurate device capacitance characterization more important than ever before. The B1507A Power Device Capacitance Analyzer meets this need, providing a complete solution for the evaluation of power device capacitance (such as input, output, and reverse transfer capacitances). The B1507A can help power device development engineers maximize product value and performance by revealing detailed device...
