100 V, 23 A, 75 mOhm – the automotive power switch
The BUK7575-100A,127: This is a through-hole part in a TO-220-3 (TO-220AB) package, designed for bolted-down mounting on a heatsink in power conversion, motor drive, and solenoid control circuits where the board sees engine-bay or transmission temperatures.
175 °C junction – where the commercial parts stop
Rated junction temperature is 175 °C, suitable for high-temperature environments. The AEC-Q101 qualification means it has passed automotive stress tests that a standard MOSFET would fail.
Gate drive and switching – the ±20 V window
Gate-source voltage is rated to ±20 V maximum. Threshold voltage is 4 V max at 1 mA drain current. Input capacitance is 1210 pF at 25 V drain-source.
