AUIRLZ44ZL

Single FETs, MOSFETs Overview

The AUIRLZ44ZL is an N-channel enhancement mode MOSFET from International Rectifier, housed in a TO-262 (D2PAK) surface-mount package. It features a maximum drain-source voltage of 55 V and a continuous drain current of 51 A at case temperature. The device exhibits a maximum on-resistance of 0.028 Ω and supports a junction operating temperature up to 175 °C. Key electrical characteristics include a typical gate charge of 33 nC at 10 V and a power dissipation rating of 80 W at case temperature.

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix 'ZL' against the manufacturer's official datasheet to confirm pinout and thermal specifications. Ensure the procurement source provides documentation confirming RoHS compliance and lead-free status as indicated by the part designation. Cross-reference the manufacturer code with Infineon Technologies records, as International Rectifier operations have been integrated into their portfolio.

Single FETs, MOSFETs Selection Notes

Select this component when a low-voltage, high-current N-channel MOSFET with logic-level gate drive is required in a surface-mount D2PAK form factor. Consider the 55 V breakdown voltage and 51 A current capacity relative to the specific load requirements. Evaluate the thermal performance based on the 80 W dissipation rating and the intended heatsinking strategy for the application environment.

Single FETs, MOSFETs Part Context

This component belongs to the IRLZ44 series of power MOSFETs manufactured by International Rectifier, now part of Infineon Technologies. The series is characterized by low on-resistance and fast switching speeds. The AUIRLZ44ZL variant specifically denotes the automotive-grade or enhanced reliability version packaged in the TO-262/IR²PACK format, designed for robust industrial and automotive power applications.

Single FETs, MOSFETs Replacement Considerations

The IRLZ44N is a closely related variant within the same family, often serving as a functional substitute. Verify that the replacement matches the TO-262 package dimensions and electrical parameters, particularly the 55 V rating and 0.028 Ω on-resistance, before implementation.
