The SI3139KDWAS-TP is a dual N-channel MOSFET manufactured by Micro Commercial Components (MCC). It integrates two independent N-channel enhancement mode field-effect transistors within a single SOT-363S surface-mount package. The device utilizes silicon technology and is designed for general-purpose switching applications requiring compact form factors.
Verify the specific suffix 'DWAS' against official MCC documentation to confirm pinout compatibility and electrical specifications. Ensure the selected variant matches the required thermal and voltage ratings for the target application, as suffixes often denote specific package or testing variations.
Select this component when a dual N-channel configuration is required in a minimal footprint. Verify that the SOT-363S package dimensions fit the PCB layout constraints. Confirm that the dual-channel architecture meets the circuit's isolation requirements between the two channels.
This part belongs to the SI3139 series of dual MOSFETs from Micro Commercial Components. It serves as a compact alternative to discrete single-channel transistors, reducing board space and assembly complexity in designs requiring multiple N-channel switching elements.
