The 2SK3019 is a single-channel N-channel MOSFET manufactured by Micro Commercial Components (MCC) using silicon technology. It is housed in a SOT-523 surface-mount package. The device features a drain-source voltage rating of 30V and a continuous drain current capacity of 100mA. Key electrical parameters include a maximum gate-source voltage of ±20V, a typical gate threshold voltage of 1.5V, and an on-resistance of 4 ohms at VGS=10V and ID=500mA. The component supports an operating junction temperature range from -55°C to +150°C and offers ESD protection up to 2kV (HBM).
Verify the authenticity of the 2SK3019HE3-TP part number against official MCC documentation. Confirm that the ordering suffix corresponds to RoHS compliance as indicated in the datasheet. Ensure procurement channels are authorized distributors to avoid counterfeit components. Check for specific packaging requirements such as tape and reel quantities if applicable.
Select this component for low-voltage switching applications requiring a compact SOT-523 footprint. Consider the 30V drain-source voltage limit and 100mA continuous current capability when designing circuits. Evaluate the thermal resistance of 436°C/W for heat dissipation needs in still air environments. Verify compatibility with logic levels given the 1.5V typical gate threshold voltage.
This MOSFET belongs to the 2SK3019 series produced by Micro Commercial Components. It utilizes standard silicon planar technology optimized for general-purpose switching. The SOT-523 package provides a small form factor suitable for space-constrained portable electronics and consumer devices.
