AUIRF540ZS is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists Infineon Technologies. Its product description is MOSFET N-CH 100V 36A D2PAK. Review the specifications below when checking this part for your BOM.
The AUIRF540ZS is an automotive-grade N-channel HEXFET power MOSFET in a D2-Pak (TO-263AB) package. It features a maximum drain-source voltage of 100V and a continuous drain current of 36A at 25°C case temperature. The device exhibits a typical on-resistance of 21mΩ, with a maximum rating of 26.5mΩ at VGS=10V. It supports a junction temperature range from -55°C to +175°C and includes repetitive avalanche capability up to Tjmax.
Verify the specific ordering suffix 'S' corresponds to the D2-Pak tube or tape-and-reel configuration required for your assembly line. Confirm that the component meets the exact AEC-Q101 qualification level mandated by your system design specifications before finalizing procurement orders.
Select this component when designing circuits that require robust automotive-grade reliability combined with low conduction losses. Ensure the thermal management solution can handle the specified junction-to-case thermal resistance. Verify that gate drive voltages remain within the ±20V absolute maximum ratings during all operating conditions.
This part belongs to Infineon's HEXFET family of power MOSFETs. It shares core electrical characteristics with the through-hole AUIRF540Z variant but utilizes a surface-mount D2-Pak package. Both variants are designed specifically for demanding automotive environments requiring high efficiency and thermal resilience.
The AUIRF540Z serves as a direct pin-compatible alternative if a through-hole TO-220AB package is preferred over the surface-mount D2-Pak form factor.
