Abstract
A method includes coupling a gate pulse generator to a gate terminal of a power transistor device under test, coupling a drain pulse generator to a drain terminal of the power transistor device under test; for a first set of test conditions, activating the drain pulse generator for each of the test conditions to apply a voltage pulse to the drain terminal, and for each of the test conditions, applying a voltage pulse to the gate terminal, the gate pulse rising only after the drain pulse falls below a predetermined threshold; for a second set of test conditions, applying a voltage pulse to the drain terminal, and applying a voltage pulse to the gate terminal, the drain pulse generator and the gate pulse generator both being active so that there is some overlap; and measuring the drain current into the power transistor device under test. An apparatus is disclosed.
