Overview

The STN2NF10 is an N-channel 100V STripFET II Power MOSFET in a SOT-223 package, designed for efficient power switching in space-constrained layouts. It provides a drain current capacity of 2.4A and is characterized by low gate charge and 100 percent avalanche testing, ensuring reliability under rugged conditions.

Why Choose This Part

The SOT-223 package offers a compact footprint with a thermal pad capable of 3.3W power dissipation. Its high 100V rating and exceptional dv/dt capability make it more resilient against voltage transients than standard 60V MOSFETs.

Applications

DC-DC Converters
Used as a primary or secondary side switch in low-power buck or boost conversion stages.
Load Switching
Ideal for high-side or low-side switching of 24V to 48V power rails in industrial equipment.
LED Dimming Control
Suitable for driving high-voltage LED strings where fast switching and high breakdown voltage are required.
Solenoid and Relay Drivers
Provides the 100V headroom necessary to safely handle inductive spikes in 12V or 24V control circuits.

Getting Started

Ensure the SOT-223 tab is soldered to a large copper plane for optimal thermal management, as power dissipation is highly dependent on PCB cooling. Reference the gate charge specifications to select appropriate gate resistors for desired switching speeds and to minimize EMI.
