VND5N07

VND5N07 Description

The VND5N07 from STMicroelectronics is a low-side power switch designed for general-purpose load driving applications. Part of the OMNIFET II™ and VIPower™ series, this N-channel MOSFET-based driver integrates advanced protection features in a compact DPAK surface-mount package. With a maximum load voltage of 55V and an output current capability of 3.5A, it is optimized for robust performance in demanding environments. The device operates without an external supply voltage, simplifying system design while offering low Rds(on) (200mΩ max) for efficient power handling.

VND5N07 Features

• High Integration: Combines a power MOSFET with built-in protection (current limiting, over-temperature, and over-voltage) in a single package.
• Efficient Switching: Low Rds(on) (200mΩ max) minimizes conduction losses, enhancing thermal performance.
• Robust Protection: Fixed current limiting (3.5A max), thermal shutdown, and over-voltage clamp ensure reliability in fault conditions.
• Simplified Design: No external Vcc/Vdd required, reducing component count and PCB space.
• Industry-Standard Package: DPAK (TO-252) offers mechanical durability and compatibility with automated assembly.
• Automotive-Grade Reliability: Though obsolete, its legacy design meets stringent AEC-Q101-like robustness for harsh environments.

VND5N07 Applications

• Automotive Systems: Ideal for relay replacements, lamp drivers, and solenoid control due to high voltage tolerance and protection features.
• Industrial Load Switching: Used in motor control, actuator drives, and power distribution where low Rds(on) and fault protection are critical.
• Consumer Electronics: Suitable for battery-powered devices, LED drivers, and DC-DC converters requiring compact, efficient switching.
• HVAC & Appliances: Protects against overloads and short circuits in fan controllers or valve drivers.

Conclusion of VND5N07

The VND5N07 excels in high-current, high-voltage switching with integrated safeguards, making it a reliable choice for legacy designs. While obsolete, its combination of efficiency, protection, and ease of use remains valuable for systems requiring durable load drivers. Engineers seeking modern alternatives should consider STMicroelectronics' newer VIPower™ offerings, but the VND5N07’s proven performance ensures continued relevance in repair or long-lifecycle applications.
