WebAlong with the drain-source voltage (VDS) ramp test, the High Temperature Reverse Bias (HTRB) test is one of the most common reliability tests for power devices. In a VDS ramp test, as the drain-source voltage is stepped from a low voltage to a voltage that’s higher than the rated maximum drain-source voltage, specified device parameters are ... WebThe collector-emitter leakage current was continuously monitored during the test. When latching of the IGBT was imminent, as was evidenced by the loss of gate control and increased collector-emitter leakage, the aging process was stopped. The collector-emitter voltage was increased from 4 to 6.5 volts during the test.
