STGB20N45LZAG

STGB20N45LZAG is a high-performance N-channel Power MOSFET manufactured by STMicroelectronics, designed for efficient power management in demanding applications. It features a maximum drain-source voltage (VDS) of 450 V, allowing it to handle high-voltage circuits commonly found in industrial and consumer electronics. The device exhibits a low on-state resistance (RDS(on)) of 0.18 Ω at VGS = 10 V, ensuring minimal conduction losses and improved energy efficiency. With a continuous drain current (ID) rating of 20 A at 25°C junction temperature, it supports robust operation under heavy load conditions. This MOSFET incorporates a trench technology structure that enhances switching speed and reduces gate charge (Qg), making it suitable for high-frequency switching applications such as switch-mode power supplies (SMPS), DC-DC converters, and motor drives. Its optimized gate threshold voltage (VGS(th)) range from 2.0 to 4.0 V ensures reliable turn-on with standard logic-level drivers, simplifying integration into digital control systems. The device also offers excellent thermal performance due to its TO-220AB package, which facilitates effective heat dissipation through direct mounting on heatsinks. Designed for reliability and durability, the STGB20N45LZAG includes built-in avalanche ruggedness and safe operating area (SOA) protection, enabling it to withstand transient overcurrents and voltage spikes common in real-world environments. These features make it ideal for use in automotive systems, renewable energy inverters, and industrial power supplies where long-term stability and safety are critical. The component’s advanced design minimizes switching and conduction losses, contributing to higher system efficiency and reduced cooling requirements. Its compatibility with standard gate drive circuits and low gate charge support fast switching transitions, reducing electromagnetic interference (EMI) and improving overall system performance. Additionally, the device meets RoHS compliance standards, aligning with environmental regulations and sustainable manufacturing practices.
