AUIRFS4310Z

AUIRFS4310Z Description

The AUIRFS4310Z from Infineon Technologies is a N-channel MOSFET designed for high-power switching applications. With a 100V drain-to-source voltage (Vdss) and 120A continuous drain current (Id), it delivers robust performance in demanding environments. This HEXFET® series device features an ultra-low on-resistance (Rds(on)) of 6mΩ at 75A, 10V, minimizing conduction losses and improving efficiency. Packaged in a D2PAK (TO-263) surface-mount form factor, it is optimized for thermal management, supporting a maximum power dissipation of 250W (Tc).

AUIRFS4310Z Features

• Low Rds(on): 6mΩ @ 75A, 10V ensures reduced power loss and higher efficiency.
• High Current Handling: 120A continuous drain current (Id) at 25°C.
• Fast Switching: Gate charge (Qg) of 170nC @ 10V and input capacitance (Ciss) of 6860pF @ 50V enable rapid switching performance.
• Robust Construction: ±20V gate-to-source voltage (Vgs) tolerance enhances reliability in high-noise environments.
• Thermal Efficiency: D2PAK package with excellent thermal dissipation (250W max).
• Compliance: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited) for environmental and handling reliability.

AUIRFS4310Z Applications

The AUIRFS4310Z excels in high-current DC-DC converters, motor control systems, and power supply units where low conduction loss and high efficiency are critical. Its high Vdss (100V) and low Rds(on) make it ideal for:

• Automotive systems (e.g., electric vehicle powertrains, battery management).
• Industrial inverters and switching regulators.
• Uninterruptible power supplies (UPS) and solar inverters.
• High-frequency switching circuits requiring minimal losses.

Conclusion of AUIRFS4310Z

The AUIRFS4310Z is a high-performance N-channel MOSFET offering low Rds(on), high current capability, and excellent thermal management, making it a top choice for power electronics designers. While obsolete, its specifications remain competitive for legacy or specialized applications requiring 100V/120A operation. Its D2PAK package and Infineon’s HEXFET® technology ensure reliability in demanding environments, from automotive to industrial power systems.
