Additional Details:

The UPA2352BT1G-E4 is characterized by its drain-source voltage (VDS), gate-source voltage (VGS), and drain current (ID). Consult the datasheet for the specific ratings. Thermal resistance junction to ambient (RθJA) is an important parameter. The gate charge affects switching performance. It is packaged for surface mounting to printed circuit boards (PCBs) and requires careful attention to soldering techniques and thermal management to ensure reliable operation. The datasheet provides information on the recommended soldering profile.
