High-Power MOSFET Characterization using the Keysight B1505
应用文章
The Keysight Technologies, Inc. B1505A Power Device Analyzer/Curve Tracer is a powerful tool for measuring and characterizing devices such as high-power MOSFETs. The B1505A’s wide measurement range (1500 A and 10 kV) and advanced features combine to provide an efficient power device measurement solution.
The B1505A supports several new external modules that greatly improve its measurement range. These include: an ultra high current unit (UHCU) with a maximum output of 1500 A, a high voltage medium current unit (HVMCU) with a maximum output range of 2.5 A/2200 V and an ultra high voltage unit (UHVU) with a maximum output of 10 kV. These capabilities provide state of the art accuracy, flexibility and ease-of-use for characterizing power devices such as high-power MOSFETs.
With its improved measurement range, the B1505A can measure the majority of power devices as shown in Figure 1. This figure shows the voltage versus current output ranges of typical B1505A modules for high power applications.
Both the UHCU and HVMCU modules possess a 10 μs high-power pulsing capability that allows more precise measurements by eliminating device self heating effects.
