Minimize Measurement Error Through Proper Fixture Design

Power semiconductor devices are available in a wide variety of package styles that require dedicated fixtures for electrical characterization. Engineers developing custom adapters must design a printed circuit board (PCB), select an appropriate socket, and implement Kelvin connections for accurate IV, CV, and gate charge measurements.

The measurement fixture should satisfy voltage, current, clearance, creepage, thermal, and wiring requirements while minimizing residual resistance and electromagnetic coupling. Following these design practices enables reliable characterization of packaged power devices using the power device analyzer platform.

Custom Socket Module Solution for Power Device Characterization

The solution combines the Keysight Power Device Analyzer / Curve Tracer with the Universal Socket Module to support custom fixture development for non-standard power device packages. The application recommends PCB dimensions, Kelvin sensing, high-current routing, clearance and creepage guidelines, cable selection, and optional circuitry for gate charge measurements. Together, these practices enable accurate and repeatable characterization of packaged power devices.
