VNQ5E250AJ-E

The VNQ5E250AJ-E is a high-performance N-channel enhancement-mode power MOSFET manufactured by STMicroelectronics, designed for efficient switching applications in modern power electronics. It features a low on-resistance of 250 mΩ at VGS = 10 V, enabling minimal conduction losses and high energy efficiency in demanding environments. The device operates with a maximum drain-source voltage (VDS) of 60 V, making it suitable for mid-voltage power conversion systems. This MOSFET is constructed using advanced trench technology, which enhances current handling capability while maintaining excellent thermal performance. It supports a continuous drain current (ID) of up to 8 A at 25°C junction temperature, ensuring reliable operation under heavy load conditions. The gate threshold voltage (VGS(th)) ranges from 1.0 to 2.5 V, allowing compatibility with standard logic-level drivers and simplifying integration into digital control circuits. Key electrical characteristics include a total gate charge (Qg) of 13 nC at VGS = 10 V, which contributes to fast switching speeds and reduced switching losses—critical for high-frequency applications such as DC-DC converters and motor drives. The device also exhibits low output capacitance (Coss ≈ 490 pF), improving dynamic performance and reducing electromagnetic interference (EMI). Designed for robust reliability, the VNQ5E250AJ-E includes built-in avalanche ruggedness and safe operating area (SOA) protection, enhancing resilience against transient overloads and short-circuit events. Its TO-220AB package ensures effective heat dissipation, supporting long-term operational stability in industrial and automotive environments. This component is widely used in applications such as power supplies for consumer electronics, battery management systems, LED lighting drivers, and small motor control units. It meets stringent industry standards including AEC-Q101 for automotive use and RoHS compliance for environmentally responsible manufacturing. The combination of high efficiency, compact footprint, and durable design makes the VNQ5E250AJ-E an ideal choice for engineers seeking performance and reliability in space-constrained, high-efficiency power solutions.
