8205A Specs and Replacement
8205A is a popular dual N-channel MOSFET commonly used in compact power-management circuits, especially in lithium-ion battery protection boards. It integrates two MOSFETs in a single SOT23-6 package, enabling efficient high-side or low-side switching within limited PCB space. The device typically features a low Rds(on), which minimizes conduction losses and heat generation during high-current operation. Its drain–source voltage rating of about 20V and continuous drain current capability of 4A make it suitable for portable electronics, DC-DC converters, load switches, battery pack BMS designs. The 8205A also offers fast switching characteristics thanks to low gate charge, improving overall system efficiency. Its integration of two matched MOSFETs simplifies circuit design, reduces component count, enhances reliability in compact power applications.
