Additional Details

The AUIRFR48ZTR typically comes in a DPAK (TO-252) or similar surface-mount package, making it suitable for automated assembly processes. Key specifications include the drain-source voltage (VDS), gate-source voltage (VGS), drain current (ID), and on-resistance (RDS(on)). The VDS indicates the maximum voltage the MOSFET can withstand between the drain and source terminals, while VGS specifies the maximum voltage between the gate and source terminals. The ID represents the maximum continuous current the MOSFET can handle, and RDS(on) indicates the resistance between the drain and source terminals when the MOSFET is turned on. For the precise ratings, operating conditions, and temperature characteristics, consulting the Infineon Technologies datasheet for the AUIRFR48ZTR is essential. The MOSFET utilizes a metal-oxide-semiconductor structure to control the flow of current between the drain and source terminals.
