The Keysight Technologies, Inc. B1505A Power Device Analyzer/Curve Tracer is a powerful tool for measuring and characterizing power devices, with many advanced features that improve measurement efficiency and accuracy.
The B1505A employs Source/Measure Unit (SMU) technology and has 40 A and 3 kV sourcing capability. This makes it much easier to apply precise currents and voltages to a device and to perform fast and accurate parameter extraction than is possible with a traditional analog curve tracer.
The B1505A can perform accurate capacitance versus voltage (CV) measurement at up to 3 kV of DC bias. In addition, during high-voltage CV measurement you can use the B1505A’s available SMUs to bias non-measurement terminals to facilitate the extraction of complex CV parameters. The B1505A makes it easy to directly measure MOSFET data sheet capacitance parameters such as Ciss, Coss and Crss.
EasyEXPERT, the GUI-based software resident on the B1505A, supports the automatic extraction of Power MOSFET parameters (including the auto-placement of lines and markers), eliminating the need for manual post-measurement adjustments. The B1505A is a powerful replacement for traditional curve-tracers that provides both improved test efficiency and measurement accuracy. This application note explains how to use the B1505A to measure the typical DC and capacitance parameters of power MOSFET devices.
