Parameter and Device Analyzers, Curve Tracers

A curve tracer is a comprehensive tool designed for power electronics circuit designers. It helps in selecting the appropriate power devices by evaluating all relevant parameters under various operating conditions. This includes measuring IV characteristics like breakdown voltage and on-resistance, as well as FET parameters such as capacitance, gate charge, and power loss. For more information, refer to this Power Device Analyzer / Curve Tracer for Circuit Design brochure for more information.

A power device analyzer is a specialized measurement instrument designed to characterize and evaluate power semiconductor devices. It provides a complete solution for analyzing critical parameters of power devices, such as transistors, diodes, and other components used in power electronics.

A Curve Tracer specifically tests semiconductor devices by applying a series of voltages or currents to plot the current-voltage (I-V) characteristics, providing insights into the device's operational behavior. A Source Measure Unit (SMU) is a more versatile module that operates as a voltage or current source/sink across all four quadrants. It's integrated into complex testing systems to perform various electrical measurements with precise control and measurement capabilities of both voltage and current. While a Curve Tracer focuses on plotting I-V curves, an SMU offers flexibility in controlling and measuring voltage and current suitable for a broader range of testing and measurement applications. Refer to this Power Device Analyzer/Curve Tracer application note for more information.

A curve tracer is used to visually display and analyze the current-voltage (I-V) characteristics of electronic components, such as transistors, diodes, and power devices. It applies a varying voltage or current to the device under test (DUT) and plots the corresponding current or voltage response as a curve. This allows engineers and technicians to quickly assess the performance, identify defects, and understand the behavior of components under different conditions, making it a valuable tool in both design and troubleshooting.

I-V curve tracers work by applying a varying voltage or current to a device under test (DUT) and measuring the corresponding current or voltage. The tracer typically sweeps the voltage (or current) over a specified range while continuously recording the resulting current (or voltage). This data is then plotted on a graph showing the relationship between current and voltage. The I-V curve provides insight into the electrical characteristics of the component, such as threshold voltage, breakdown voltage, and overall performance under different operating conditions.
