00 — Overview

What the HL2302 family does

The HL2302 is an N-channel MOSFET in the SOT-23 package featuring Trench Power MV technology. It supports a 20 V drain-source voltage, 3 A continuous drain current, and less than 45 mΩ on-resistance at 4.5 V gate drive. The device handles 8 A pulsed current and operates from -55 to +150 °C. It serves as a fast switching voltage-controlled signal suitable for battery-operated systems, solid-state relays, and direct TTL/CMOS logic-level interfaces.
