HEXFET N-channel for high-current switching
The Infineon AUIRF2903Z is a 30 V, 160 A N-channel HEXFET MOSFET in a TO-220AB through-hole package, designed for low on-resistance switching in power conversion and motor drive circuits.
Thermal and environment envelope
The 290 W power dissipation rating is the absolute maximum under ideal heatsinking; real-world continuous dissipation depends on the heatsink thermal resistance and airflow, so size the heatsink for the actual switching losses.
Gate drive and threshold
Maximum gate-source voltage is ±20 V.
