QM4803D-VB Product Introduction
QM4803D-VB is a high-performance common-source N+P channel MOSFET in TO252-4L package, designed for efficient power management and switching applications. It supports a maximum drain-source voltage (VDS) of ±40V and a maximum drain current (ID) of ±50A, which is very suitable for circuits requiring bipolar current. The low on-resistance (RDS(ON)) of QM4803D-VB enables it to have excellent thermal performance and energy efficiency in high-frequency applications, and is particularly suitable for demanding power conversion fields.
