STMicroelectronics STD4N90K5: High-Performance Power MOSFET for Demanding Applications
In the evolving landscape of power electronics, STMicroelectronics continues to set benchmarks with its MDmesh™ series, specifically designed to address the challenges of high-voltage applications. The STD4N90K5 N-Channel MOSFET exemplifies this commitment to innovation, offering engineers a robust solution for power conversion systems requiring exceptional voltage handling capabilities and thermal efficiency. This surface-mount transistor, housed in a compact DPAK package, combines advanced silicon technology with optimized design parameters to deliver reliable performance in industrial, automotive, and consumer electronics domains.
Technical Excellence in Power Management
Engineered for high-voltage environments, the STD4N90K5 features a remarkable 900V drain-source voltage rating that positions it as an ideal candidate for power factor correction (PFC) circuits, switched-mode power supplies (SMPS), and motor control systems. Its 2.1Ω maximum on-state resistance at 10V gate-source voltage ensures minimal conduction losses, while the 5.3nC gate charge specification enables rapid switching transitions. These characteristics translate to improved energy efficiency and reduced thermal stress on components, crucial for maintaining system reliability in high-frequency operations.
The device's thermal performance is further enhanced through its 60W power dissipation rating at case temperature, allowing it to maintain operational stability under demanding load conditions. With ±30V gate-source voltage protection, the transistor demonstrates exceptional tolerance to voltage transients, minimizing the risk of gate oxide breakdown in real-world applications.
