Additional Details:

The SiS412DN typically features a drain-source voltage (VDS) rating of -20V and a continuous drain current (ID) rating of around -4.7A. The on-resistance (RDS(on)) is typically very low, in the range of tens of milliohms. The gate threshold voltage (VGS(th)) is usually between -1V and -3V, making it suitable for logic-level gate drive. The package is commonly a PowerPAK SO-8. The power dissipation is typically around 2W. This P-Channel MOSFET is designed for efficient power management in space-constrained applications. Its low on-resistance and fast switching speeds make it suitable for high-frequency DC-DC converters and load switches.
