DVDS-05A20V
DVDS tester
Description of test regulation - △Vds
△Vds from :[MIL750 3161.1]
| Purpose | The purpose of this test is to measure the thermal impedance of the MOSFET under the specified conditions of applied voltage, current, and pulse duration. The temperature sensitivity of the forward voltage of the source drain diode is used as the junction temperature indicator. This method is particularly suitable to enhancement mode, power MOSFET's having relatively long thermal response times. This test method may be used to measure the thermal response of the junction to a heating pulse, to ensure proper die mount down to its case, or the dc thermal resistance, by the proper choice of the pulse duration and magnitude of the heating pulse. |
| Guide line | According to theory, please see below drawing. Current flows from left to device and heating current flows from right to device. |
