Infineon IPZ40N04S5L7R4ATMA1 40V OptiMOS 5 Power MOSFET: Powering the Next Generation of High-Efficiency Systems

In the rapidly evolving world of electronics, the quest for higher efficiency, greater power density, and improved thermal performance is relentless. At the heart of many advanced power conversion systems—from server SMPS and DC-DC converters to motor drives and battery management—lies the power MOSFET. The Infineon IPZ40N04S5L7R4ATMA1, a 40V OptiMOS™ 5 Power MOSFET, stands out as a premier component engineered to meet these demanding challenges.

This device is a testament to Infineon's commitment to pushing the boundaries of power semiconductor technology. The OptiMOS™ 5 series represents a significant leap forward from its predecessors, offering a superior blend of key performance characteristics that directly translate into system-level benefits.

Unmatched Efficiency for Reduced Power Loss

The most compelling feature of the IPZ40N04S5L7R4ATMA1 is its exceptionally low figure-of-merit (FOM), which is the product of the on-state resistance (RDS(on)) and the gate charge (Qg). With an ultra-low RDS(on) of just 1.7 mΩ (max. at 10 Vgs), conduction losses are minimized. Simultaneously, its optimized gate charge ensures that switching losses are drastically reduced. This combination is crucial for high-frequency switching applications, allowing designers to increase switching frequencies without a punitive efficiency loss, which in turn enables the use of smaller passive components like inductors and capacitors.

Enhanced Power Density and Thermal Performance

The reduction in both static and dynamic losses means that systems can operate cooler. The MOSFET's superior thermal characteristics, facilitated by its advanced package technology, allow for better heat dissipation. This enables the design of more compact products with higher power density, as less space is required for heat sinks and cooling solutions. Engineers can create smaller, lighter, and more powerful end-products, a critical advantage in today's market.

Robustness and Reliability

Beyond pure performance metrics, the IPZ40N04S5L7R4ATMA1 is designed for robustness. It offers a high level of durability under demanding operating conditions, including excellent avalanche ruggedness and a wide operational temperature range. This reliability ensures long-term system stability and reduces the risk of failure in critical applications.

Ideal Applications

This MOSFET is perfectly suited for a wide array of applications, including:

High-frequency DC-DC conversion in computing and telecom infrastructure.

Motor control solutions for industrial drives, drones, and power tools.

Synchronous rectification in switch-mode power supplies (SMPS).

Battery protection and management systems in portable devices and energy storage.
