Additional Details:

The UT2305AL typically has a drain-source voltage (VDS) rating of -30V and a continuous drain current (ID) rating of around -3.1A (depending on datasheet and testing conditions). The on-resistance (RDS(ON)) at VGS = -10V is around 50mΩ, and RDS(ON) at VGS = -4.5V is around 80mΩ. The gate threshold voltage is typically between -1V and -3V. The device is usually supplied in a SOT-23 package. For accurate and complete specifications, including thermal resistance, gate charge characteristics, and safe operating area, it is essential to consult the manufacturer's datasheet. Proper thermal management is crucial for reliable operation at higher currents. This MOSFET offers a good balance between switching speed, on-resistance, and gate charge, making it a suitable choice for a variety of power management applications.
