The PJA3446-AU from PANJIT Semiconductor is an Automotive Qualified N-Channel Enhancement Mode MOSFET that has been specifically designed for switch load applications. It has a drain-source breakdown voltage of over 40 V, a gate threshold voltage of 1.8 V, and a drain-source on-resistance of less than 51 milli-ohms. This AEC-Q101-qualified MOSFET has a continuous drain current of up to 4.1 mA and a power dissipation of less than 125 W. It offers outstanding performance and efficiency due to its high switching speed, low gate charge, and low reverse transfer capacitance. This RoHS-compliant MOSFET is available in a surface-mount package that measures 3.04 x 1.40 x 1.10 mm.
