Infineon SPP42N03S2L-13: N-Channel MOSFET for High-Efficiency Power Management
In the realm of modern electronics, achieving high efficiency in power management is a critical design objective. The Infineon SPP42N03S2L-13 stands out as a premier N-Channel MOSFET engineered specifically to meet this challenge. This power MOSFET is a key component in a wide array of applications, from server power supplies and motor controls to high-frequency DC-DC converters, where minimizing energy loss and maximizing thermal performance are paramount.
At the core of this device's superior performance is its advanced OptiMOS™ technology. This proprietary process from Infineon enables an exceptionally low on-state resistance (R DS(on)) of just 1.3 mΩ (max. at V GS = 10 V). This ultra-low R DS(on) is crucial as it directly translates to reduced conduction losses. When the MOSFET is switched on, it behaves more like a very small resistor, wasting minimal power as heat. This characteristic is vital for improving the overall efficiency of a power system, leading to cooler operation and potentially smaller heatsinks.

Furthermore, the SPP42N03S2L-13 is designed for robust switching performance. It features a low gate charge (Q G) and low effective output capacitance (C OSS(eff)), which are essential for achieving fast switching speeds. Fast switching minimizes the transition time between the on and off states, thereby reducing switching losses—a significant source of inefficiency in high-frequency circuits. This combination of low R DS(on) and excellent switching characteristics makes this MOSFET ideal for demanding synchronous rectification stages in switch-mode power supplies (SMPS).
The device is rated for a drain-source voltage (V DS) of 30 V and a continuous drain current (I D) of 180 A, demonstrating its capability to handle high power levels. Housed in a TO-263 (D2PAK) surface-mount package, it offers an excellent footprint-to-performance ratio, providing strong power dissipation in a compact form factor suitable for automated assembly processes. This package is renowned for its mechanical robustness and reliable power cycling capability.
ICGOOODFIND: The Infineon SPP42N03S2L-13 is a top-tier N-Channel MOSFET that sets a high standard for efficiency and reliability in power management. Its exceptional blend of ultra-low on-resistance, fast switching capability, and high current handling makes it an indispensable component for designers striving to create more efficient, cooler-running, and compact power solutions.
