The KFJ4B0421ZL from Nuvoton Technology is an Automotive-Qualified P-channel MOSFET. It has a drain-source breakdown voltage of over -40 V, a gate threshold voltage of -2 V, and a drain-source on-resistance of less than 74 milli-ohms. This AEC-Q101-qualified MOSFET has a continuous drain current of up to -4.2 A and a power dissipation of less than 1.7 W. It benefits from embossed-type thermo-compression sealing. This RoHS-compliant MOSFET is available in a surface-mount package that measures 1.2 x 1.2 x 0.1 mm and is ideal for automotive applications.
