Product introduction：
**
STP3N90-VB is a single N-channel MOSFET in TO220 package, designed for high-voltage switching applications, using advanced SJ_Multi-EPI technology. With a drain-source voltage (V_DS) of up to 900V and a drain current (I_D) of up to 5A, this MOSFET is suitable for power electronic devices that require high voltage and high withstand voltage. Its threshold voltage (V_th) is 3.5V, and the gate-source voltage (V_GS) can reach a maximum of ±30V. The on-resistance (R_DS(ON)) of STP3N90-VB is 1500mΩ (at V_GS = 10V), which can provide high switching efficiency and reliability while ensuring good current transmission. This MOSFET is suitable for high-voltage power conversion, switching power supplies and other fields, and is widely used in power management in power electronics, industrial equipment, and electric vehicles.
