The SIX3139KA-TP is a silicon N-channel MOSFET manufactured by Micro Commercial Components. It is housed in an SOT-23 surface-mount package and operates as a single enhancement-mode device. The component supports a drain-source voltage of 60 V and a continuous drain current of 1.5 A. Its maximum on-resistance is specified at 0.24 ohms. The gate-source voltage range extends from -8 V to +8 V, with a threshold voltage typically around 1 V. Power dissipation reaches 500 mW, and the operating temperature spans from -55°C to +150°C.
Verify the specific datasheet revision when sourcing this component, as electrical characteristics may vary between manufacturing lots or updates. Confirm that the SOT-23 pinout matches your PCB layout requirements before finalizing procurement. Ensure compliance with RoHS directives if required by your project specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Select this MOSFET when a balance of moderate current handling and low resistance is needed in a small package. Compare the 0.24 ohm on-resistance against alternative devices to ensure thermal performance meets system constraints. Consider the 60 V rating to provide adequate headroom for supply voltage fluctuations. Evaluate the gate charge parameters if high-frequency switching is a primary design requirement.
This component belongs to the SIX3139KA series of N-channel MOSFETs from Micro Commercial Components. The series focuses on providing reliable switching performance in standard surface-mount packages. These devices are designed for general-purpose applications requiring efficient power control within limited physical spaces on electronic assemblies.
