IRLL3303PBF

IRLL3303PBF Description

The IRLL3303PBF from Infineon Technologies is an N-channel HEXFET® MOSFET designed for high-efficiency power management applications. With a 30V drain-to-source voltage (Vdss) and 4.6A continuous drain current (Id), this surface-mount MOSFET is optimized for low-loss switching in compact designs. Its low on-resistance (Rds(on)) of 31mOhm at 10V ensures minimal conduction losses, while the gate charge (Qg) of 50nC at 10V enables fast switching performance. Packaged in SOT-223, it balances thermal performance with space-saving benefits, making it ideal for modern electronics.

IRLL3303PBF Features

• Low Rds(on): 31mOhm at 4.6A, 10V reduces power dissipation.
• High Drive Voltage Range: 4.5V to 10V for compatibility with logic-level and standard gate drives.
• Robust Vgs(max): ±16V gate tolerance enhances reliability in noisy environments.
• Low Gate Threshold (Vgs(th)): 1V at 250µA ensures efficient turn-on.
• Low Input Capacitance (Ciss): 840pF at 25V minimizes switching losses.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.
• 1W Power Dissipation: Suitable for thermally constrained applications.
