AUIRL1404Z

Single FETs, MOSFETs Overview

The AUIRL1404Z is an automotive-grade N-channel HEXFET power MOSFET in a TO-220AB package. It features a maximum drain-source voltage of 40V and continuous drain currents of 180A (silicon limited) or 160A (package limited). The device exhibits ultra-low on-resistance, with typical and maximum values of 2.5mΩ and 3.1mΩ respectively at VGS=10V. Key electrical parameters include a gate charge of 75nC, single pulse avalanche energy of 190mJ, and a junction temperature range of -55°C to +175°C.

• DC-DC converter circuits
• Power management modules

Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix matches the required package type, as variants exist for D2Pak and TO-262. Confirm that the component meets the necessary AEC-Q101 qualification requirements for your specific automotive application environment. Ensure thermal management designs account for the specified junction-to-case resistance values under board-mounted conditions.

Single FETs, MOSFETs Selection Notes

Select this component when automotive reliability and logic-level compatibility are critical. The TO-220AB package suits through-hole mounting and higher current handling compared to surface-mount alternatives. Evaluate the trade-off between the 160A package-limited current and the 180A silicon-limited rating based on your PCB thermal design and lead mounting arrangements.

Single FETs, MOSFETs Part Context

This part belongs to Infineon's HEXFET family of power MOSFETs designed for robust performance in demanding environments. The 'AU' prefix indicates it has passed automotive qualification standards, distinguishing it from standard industrial versions. It utilizes advanced trench technology to minimize conduction losses while maintaining fast switching speeds suitable for modern power electronics.

Single FETs, MOSFETs Replacement Considerations

Direct replacements include the IRL1404Z for non-automotive use or the AUIRL1404ZS in a D2Pak package if surface mount is preferred. Verify pinout compatibility and ensure the substitute meets the same 40V rating and current handling capabilities.
