Product Introduction
**SFT1445-H-VB** is a single N-channel power MOSFET in a TO252 package, designed for medium voltage and current switching applications. The device has a maximum drain-source voltage (VDS) of 100V, which is suitable for switching control of lower voltage power supplies. Its maximum gate-source voltage (VGS) is ±20V, which can adapt to various driving conditions. The threshold voltage (Vth) of this MOSFET is 1.8V, which can be stably turned on at a lower gate voltage. The on-resistance (RDS(ON)) is 114mΩ (at VGS=10V), ensuring that power loss is effectively reduced during the switching process. The maximum drain current (ID) is 15A, which is suitable for switching applications that handle medium power. SFT1445-H-VB uses Trench technology, which gives it good switching characteristics and low conduction losses, and is widely used in power management, load switching, motor drive and other fields.
