## Description

The IRL540A is an N-channel power MOSFET manufactured by On Semiconductor (originally Fairchild Semiconductor). It features a drain-source breakdown voltage of 100V (minimum) and a continuous drain current of 28A at 25°C case temperature. The on-resistance is typically 0.046Ω and maximum 0.058Ω at VGS=5V and ID=14A. The device offers a gate threshold voltage range of 1.0V to 4.0V, making it suitable for logic-level drive applications.

Electrical characteristics include a typical input capacitance of 1580 pF, output capacitance of 390 pF, and reverse transfer capacitance of 180 pF at VDS=25V. Total gate charge is 54 nC at VGS=5V, with a gate-drain (Miller) charge of 38 nC. The device is rated for a maximum power dissipation of 121W at 25°C case temperature. Thermal resistance junction-to-case is 0.81°C/W.

The IRL540A is designed for rugged applications with avalanche rugged technology and lower leakage current (10 µA max at VDS=100V). It is packaged in a TO-220-3 through-hole package with three terminals (gate, drain, source). The operating junction temperature range is -55°C to 175°C.
