Additional Details:

The UT45N03L-TN3-T's datasheet specifies key parameters such as drain-source voltage (VDS), gate-source voltage (VGS), and drain current (ID). The static drain-source on-resistance (RDS(on)) is a critical parameter for determining conduction losses. Ensure proper heatsinking to maintain the device within its operating temperature range. Gate charge (Qg) is an important factor influencing switching speed and losses.
