AUIRF2804S

AUIRF2804S Description

The AUIRF2804S from Infineon Technologies is a high-performance N-channel MOSFET designed for power management applications requiring robust efficiency and thermal stability. With a 40V drain-to-source voltage (Vdss) and an impressive 195A continuous drain current (Id), this HEXFET® series device is optimized for high-current switching. Its ultra-low on-resistance (Rds(on)) of 2mOhm at 75A, 10V minimizes conduction losses, while the 300W (Tc) power dissipation ensures reliable operation under demanding conditions. Packaged in a D2PAK (TO-263) surface-mount format, it balances power density with thermal performance.

AUIRF2804S Features

• Low Rds(on): 2mOhm at 10V gate drive, enhancing efficiency in high-current paths.
• High Current Handling: 195A (Tc) rating, ideal for heavy-load applications.
• Fast Switching: Moderate gate charge (Qg) of 240nC and input capacitance (Ciss) of 6450pF, enabling efficient high-frequency operation.
• Robust Construction: ±20V Vgs tolerance and REACH/ROHS3 compliance ensure durability and environmental safety.
• Thermal Performance: D2PAK package with MSL1 (unlimited) moisture sensitivity, suitable for industrial environments.

AUIRF2804S Applications

This MOSFET excels in:

• DC-DC Converters: Leveraging low Rds(on) for minimal power loss in step-down/step-up circuits.
• Motor Drives: High current capability supports brushed/brushless motor control in automotive/industrial systems.
• Power Supplies: Efficient switching in server/telecom PSUs and uninterruptible power supplies (UPS).
• Battery Management: Ideal for high-current discharge protection in Li-ion/pack systems.

Conclusion of AUIRF2804S

The AUIRF2804S stands out for its high current density, low conduction losses, and rugged packaging, making it a top choice for power electronics designers. While marked obsolete, its performance benchmarks—such as 2mOhm Rds(on) and 195A Id—remain competitive for legacy or cost-sensitive projects. Its D2PAK format ensures compatibility with automated assembly, while Infineon’s HEXFET® technology guarantees reliability in mission-critical applications.
