Product introduction：
Product Introduction: STP40N03L-20-VB
STP40N03L-20-VB is a high-performance N-channel power MOSFET in TO220 package, designed for low-voltage, high-current switch control applications. The maximum drain-source voltage (V_DS) of this model is 30V, which is suitable for low-voltage power supplies and power conversion systems that require high current handling. STP40N03L-20-VB uses Trench technology and has extremely low on-resistance (R_DS(ON)), which are 9mΩ@V_GS=4.5V and 6mΩ@V_GS=10V, respectively, which can significantly reduce power loss and improve circuit efficiency. Its maximum drain current (I_D) is 80A, which is very suitable for applications requiring high current, high-power switching.
