The IRLL3303PBF is an N-Channel power MOSFET manufactured by Infineon Technologies (formerly International Rectifier). This HEXFET device provides a drain-source breakdown voltage of 30V and supports a continuous drain current of 4.6A at 25°C when mounted on a PCB. It is designed for surface-mount assembly in the SOT-223 package (TO-261-4, TO-261AA).
Key electrical specifications include a maximum drain-source on-resistance of 31mΩ at VGS=10V and 4.6A, and 45mΩ at VGS=4.5V and 2.3A. The device features logic-level gate drive (4.5V/10V), a total gate charge of 50nC at 10V, and input capacitance of 840pF at 25V. It can handle pulsed drain currents up to 37A and single-pulse avalanche energy of 140mJ.
Designed for fast switching and low on-resistance, the IRLL3303PBF suits power management and load switching in space-constrained boards. Its SOT-223 package includes an enlarged tab for improved thermal performance; power dissipation is rated at 1W at 25°C (PCB mount) with a junction-to-ambient thermal resistance of 120°C/W maximum. The device operates over a junction temperature range of -55°C to 150°C.
The part is marked lead-free (PbF) in the datasheet and is listed as RoHS3 compliant, with moisture sensitivity level of 1 (unlimited).
The minimum drain-source breakdown voltage is 30V.
The gate-source voltage rating is ±16V.
