AUIR33402STRL

Power Distribution Switches, Load Drivers Overview

The AUIR33402STRL is a single-channel high-side power switch manufactured by Infineon Technologies. It features an N-channel MOSFET output capable of handling a maximum continuous current of 33A with a typical on-resistance of 3 milliohms. The device operates within a load voltage range of 6V to 18V and utilizes a D2PAK-7 surface-mount package. Integrated protection mechanisms include adjustable current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). It is qualified to the AEC-Q100 standard for automotive applications.
