The EMB20N03 / B20N03 (B20 N03) is a compact N-Channel MOSFET designed for high-efficiency switching in laptop motherboards, power adapters, battery management systems, and DC-DC converter circuits. Its low RDS(on) and fast switching capability make it ideal for handling load transitions and delivering stable current in compact electronic designs. The QFN-8 package provides excellent thermal performance and minimal footprint, allowing engineers to build high-density power stages. This MOSFET is commonly used in charging paths, DC-in protection stages, VRM modules, and low-voltage switching lines found in modern laptops and portable devices. At OKSpare, we maintain IC ready stock OKSpare, IC supplier OKSpare, and IC available at OKSpare, offering genuine components at the best price, all quality tested by the OKSpare team.
