Technical Specifications:

The ZXMP3A16N8 features a maximum drain-source voltage (Vds) of 16V, a gate-source voltage (Vgs) of ±10V, and a continuous drain current (Id) that depends on the operating temperature and mounting conditions. The on-resistance (Rds(on)) is typically specified at different gate-source voltages (e.g., Vgs = -4.5V). Other key parameters include the input capacitance (Ciss), output capacitance (Coss), and gate charge (Qg). The SOT23 package has a thermal resistance that affects the maximum power dissipation.
