Additional Details:

Crucial specifications include drain-source voltage (VDS), gate-source voltage (VGS), and continuous drain current (ID). The on-resistance (RDS(on)) is a key performance indicator. Gate charge (Qg) influences switching speed. Avalanche energy (EAS) reflects its ability to withstand inductive kickback. Thermal resistance (Rth) dictates its heat dissipation capability.
