STD25NF10LA

The STD25NF10LA is a high-performance N-channel enhancement-mode MOSFET manufactured by STMicroelectronics, designed for efficient power switching applications. It features a low on-resistance of 10 mΩ at VGS = 10 V, enabling minimal conduction losses and improved energy efficiency in power conversion systems. The device is rated for a maximum drain-source voltage (VDS) of 100 V and a continuous drain current (ID) of 25 A at 25°C junction temperature, making it suitable for high-current applications such as DC-DC converters, motor drives, and battery management systems. This MOSFET incorporates a robust trench technology that enhances thermal performance and ensures reliable operation under harsh conditions. Its optimized gate charge (Qg = 63 nC typical at VGS = 10 V) allows for fast switching speeds, reducing switching losses and supporting high-frequency operation—ideal for modern power electronics requiring compact and efficient designs. The device also exhibits excellent avalanche ruggedness, providing protection against transient overvoltages commonly found in industrial and automotive environments. Packaged in a TO-220AB plastic package with a single lead, the STD25NF10LA offers ease of integration into PCB layouts while maintaining strong mechanical and thermal stability. The package design facilitates effective heat dissipation through the exposed pad, which can be soldered to a copper plane or heatsink, further enhancing thermal performance. The STD25NF10LA is widely used in applications such as switched-mode power supplies (SMPS), uninterruptible power supplies (UPS), electric vehicle chargers, and industrial automation equipment. Its low RDS(on) and high current capability make it an ideal choice for buck converters, synchronous rectification circuits, and inverter topologies where efficiency and reliability are critical. Designed for compliance with industry standards, including RoHS and REACH, the device supports environmentally responsible manufacturing practices. STMicroelectronics’ rigorous quality control ensures consistent performance across temperature ranges from -55°C to +150°C junction temperature, making the STD25NF10LA suitable for both consumer and industrial-grade applications requiring long-term reliability.
