STN3N40K3 Description

STN3N40K3 Description

The STN3N40K3 from STMicroelectronics is a 400V N-channel MOSFET belonging to the SuperMESH3™ series, designed for high-efficiency power switching applications. With a continuous drain current (Id) of 1.8A (Tc) and a low on-resistance (Rds On) of 3.4Ω @ 600mA, 10V, it delivers robust performance in compact surface-mount packages. The device features a gate charge (Qg) of 11nC @ 10V and an input capacitance (Ciss) of 165pF @ 50V, ensuring fast switching and reduced power losses. Its ±30V gate-to-source voltage (Vgs) tolerance and 4.5V threshold voltage (Vgs(th)) make it suitable for high-voltage designs. Packaged in SOT-223 (Tape & Reel), it is ideal for space-constrained applications.
