Apparatus and methods for characterizing electrical components for evaluating performance in a high voltage transient protection circuit. Impedance graphs provided by manufacturers for electrical components are typically low voltage measurements that do not necessarily accurately reflect component performance at high voltages above 150 volts. It is important to characterize and understand the behavior of these components at high voltages in order to ensure the components will protect circuitry as expected. In certain embodiments, a characterization method includes obtaining time domain voltage measurements from two terminals of a device under test (DUT) as it is exposed to high voltage transients from an electrical fast transient (EFT) generator. The time domain voltage data is transformed into frequency domain voltage data using a transform algorithm, and additional analysis is performed to derive scattering parameters, impedance, and other valuable metrics for component characterization.
