Applications
The IRF7811AVPBF is a high-performance N-channel MOSFET optimized for synchronous buck converter applications in notebook computers, portable electronics, and telecom power modules where efficiency and board space are at a premium. With 30 V breakdown voltage, 10.8 A drain current, and only 14 mΩ on-resistance, it delivers low conduction and switching losses at voltages typical of 12 V to 5 V step-down stages. It is also well-suited for load switches, motor drive bridges, and battery management systems operating from lithium-ion or 12 V bus supplies.

Frequently Asked Questions
What is the on-resistance of the IRF7811AVPBF and why does it matter for synchronous buck converter efficiency?
The IRF7811AVPBF has a maximum RDS(on) of 14 mΩ at 4.5 V gate drive. In a synchronous buck converter carrying 10 A, this yields only 1.4 W of conduction loss per switch, enabling converter efficiencies above 95% in a 30 V to 5 V application, which is critical for thermal management in notebook power stages.
What package does the IRF7811AVPBF use and how does it affect PCB layout for high-current designs?
The IRF7811AVPBF is housed in an SO-8 (JEDEC MS-012AA, JESD-30 R-PDSO-G8) surface-mount package, which occupies approximately 5 mm x 4 mm of PCB area. The compact 8-pin layout simplifies synchronous rectifier designs, allows tight driver-to-gate routing to reduce parasitic inductance, and fits standard SMT land patterns for automated reflow assembly at 10.8 A load ratings.
When is the IRF7811AVPBF a better choice than a higher-voltage MOSFET for DC-DC converter designs?
For DC-DC applications with input rails at or below 12 V, the IRF7811AVPBF 30 V breakdown voltage rating provides adequate margin without the higher RDS(on) penalty that comes with 40 V or 60 V devices. Choosing a 30 V part like the IRF7811AVPBF rather than a 60 V alternative can reduce on-resistance by 2x to 3x, directly improving efficiency at 10 A load currents in synchronous buck converters.
How does the 46 pF Crss of the IRF7811AVPBF influence switching losses at high frequencies?
The 46 pF maximum reverse transfer capacitance (Crss) of the IRF7811AVPBF limits the Miller charge required during switching transitions. At switching frequencies of 300 kHz to 1 MHz in a 12 V synchronous buck stage, the low Crss value reduces gate drive energy per cycle and keeps switching losses low, helping maintain overall converter efficiency above 90% even at elevated frequencies.
