UT4421L-S08-R-VB MOSFET Product Introduction
**UT4421L-S08-R-VB** is a single P-channel MOSFET in a **SOP8** package, designed for high-efficiency switching applications. This MOSFET uses advanced **Trench** technology, with a maximum drain-source voltage of -60V, a maximum drain current of -8A, and a low on-resistance (RDS(ON)) characteristic. Its threshold voltage (Vth) is -1.7V, which is suitable for occasions requiring low gate-source voltage operation. Due to its low RDS(ON) characteristics, this MOSFET is particularly suitable for battery management systems, load control, power management and other fields, and can provide efficient current switching functions while reducing power losses.
