With its 800V voltage rating and 9A current capacity, this device represents the perfect balance between performance and reliability.

Technical Excellence in Power Management

At the heart of this MOSFET lies ST's proprietary SuperMESH™ technology, which dramatically reduces on-resistance while maintaining exceptional switching characteristics. The device's 900mΩ Rds(on) at 10V gate drive ensures minimal conduction losses, making it ideal for high-efficiency power conversion systems. Its advanced trench gate structure optimizes electric field distribution across the die, enabling reliable operation at extreme voltage levels.

The STP10NK80Z's 72nC gate charge (Qg) at 10V gate voltage strikes an optimal balance between switching speed and drive capability. This specification makes it particularly suitable for applications requiring rapid transitions without excessive driver power consumption. The ±30V gate voltage rating provides additional design flexibility, while the 4.5V threshold voltage ensures compatibility with standard logic-level control circuits.

Design Versatility and Thermal Performance

Housed in a standard TO-220AB package, this transistor offers excellent thermal dissipation characteristics through its through-hole mounting configuration. The 190W power dissipation rating at case temperature enables operation in demanding environments without complex cooling solutions. Its wide operating temperature range (-55°C to 150°C) makes it suitable for both industrial and automotive applications where thermal stability is critical.

The device's 2180pF input capacitance at 25V Vds ensures predictable switching behavior in high-frequency circuits. This parameter, combined with the optimized gate charge characteristics, makes the STP10NK80Z particularly well-suited for switch-mode power supplies (SMPS), motor control systems, and DC-DC converters where efficiency and thermal management are paramount.

Applications Across Industries

This versatile transistor finds application in a wide range of power electronics systems. In industrial settings, it serves as the backbone of variable frequency drives and uninterruptible power supplies (UPS). Automotive engineers utilize its capabilities in on-board chargers and DC-DC converters for electric vehicles. Consumer electronics manufacturers implement it in high-power switching applications such as induction cookers and high-end audio amplifiers.

The STP10NK80Z's robust construction and STMicroelectronics' rigorous quality standards ensure long-term reliability in critical applications. Its through-hole package provides mechanical stability in environments with vibration or thermal cycling, making it a preferred choice for industrial automation equipment and automotive systems.

Future-Proof Power Solutions

As power electronics continue to evolve towards higher efficiency and compact form factors, the STP10NK80Z represents a bridge between proven technology and future requirements.
