VN5R003H-E

The VN5R003H-E is a high-performance power MOSFET from STMicroelectronics, designed for efficient switching applications in automotive and industrial systems. It features a maximum drain-source voltage (VDS) of 60 V, making it suitable for low-to-medium voltage power conversion tasks. The device offers a low on-resistance (RDS(on)) of typically 4.5 mΩ at VGS = 10 V, ensuring minimal conduction losses and high energy efficiency. This MOSFET is fabricated using advanced trench technology, which enhances gate charge characteristics and reduces switching losses. Its optimized gate threshold voltage (VGS(th)) ranges from 1.2 V to 2.5 V, enabling compatibility with low-voltage control circuits such as microcontrollers or gate drivers. The device also includes an integrated body diode with fast reverse recovery, improving reliability in inductive load applications like motor drives and DC-DC converters. Designed for robust operation in harsh environments, the VN5R003H-E meets AEC-Q101 qualification standards, making it ideal for automotive electronics including battery management systems, power steering, and onboard chargers. It supports continuous current ratings up to 70 A at 25°C junction temperature, with excellent thermal performance due to its surface-mount TO-220 package, which allows efficient heat dissipation. The device incorporates built-in protection features such as avalanche ruggedness and safe operating area (SOA) capability, enhancing system reliability under transient conditions. Its low gate charge (QG) of approximately 80 nC further contributes to fast switching speeds and reduced electromagnetic interference (EMI), critical for high-frequency switching applications. Applications include buck converters, synchronous rectification in power supplies, and load switch circuits where high efficiency and compact design are essential. The VN5R003H-E’s combination of low RDS(on), fast switching, and automotive-grade reliability makes it a preferred choice for engineers designing next-generation power management solutions in electric vehicles and industrial automation systems.
