AUIRFR3504Z Description

The AUIRFR3504Z from Infineon Technologies is an N-channel HEXFET® power MOSFET designed for high-efficiency switching applications. With a 40V drain-to-source voltage (Vdss) and 42A continuous drain current (Id), it offers robust performance in power management circuits. This surface-mount device features a low on-resistance (Rds(on)) of 9mΩ at 10V gate drive, minimizing conduction losses. Its 1510pF input capacitance (Ciss) and 45nC total gate charge (Qg) ensure fast switching, making it suitable for high-frequency applications. Although marked as obsolete, it remains a reliable choice for legacy designs due to its 90W power dissipation (Tc) and ±20V gate-source voltage (Vgs) tolerance.

AUIRFR3504Z Features

• Low Rds(on): 9mΩ @ 42A, 10V reduces power loss in high-current paths.
• High Current Handling: 42A continuous drain current supports demanding loads.
• Fast Switching: Optimized gate charge (45nC) and capacitance for efficient PWM applications.
• Robust Construction: HEXFET® technology ensures durability and thermal stability.
• Compliance: ROHS3 compliant and REACH unaffected, meeting environmental standards.
• Wide Vgs Range: ±20V gate drive flexibility enhances design compatibility.

AUIRFR3504Z Applications

Ideal for:

• DC-DC Converters: Efficient power conversion in automotive and industrial systems.
• Motor Drives: High-current switching in brushed/brushless motor controllers.
• Power Supplies: Synchronous rectification in SMPS designs.
• Battery Management: Load switching in portable and energy storage systems.
• Legacy Upgrades: Replacement for obsolete MOSFETs in existing hardware.

Conclusion of AUIRFR3504Z

The AUIRFR3504Z excels in high-current, low-loss applications, leveraging Infineon’s HEXFET® technology for reliability. While obsolete, its low Rds(on), high current capability, and fast switching make it a strong candidate for retrofits or designs prioritizing proven performance. Engineers should evaluate alternatives for new designs but can rely on this MOSFET for robust operation in power electronics.
