VNB35N07

VNB35N07 Description

The VNB35N07 from STMicroelectronics is a low-side power switch designed for general-purpose load driving applications. Part of the OMNIFET™ and VIPower™ series, this N-channel MOSFET-based IC integrates advanced protection features and robust performance in a D2PAK surface-mount package. With a maximum load voltage of 55V and an output current capability of 25A, it is engineered for high-efficiency power distribution. Though marked as obsolete, it remains relevant for legacy designs requiring reliable, high-current switching with integrated fault management.

VNB35N07 Features

• High Current Handling: Supports up to 25A continuous output current with a low Rds(on) of 28mΩ (max), minimizing conduction losses.
• Integrated Protections: Features fixed current limiting, over-temperature shutdown, and over-voltage protection, enhancing system reliability.
• Status Flag: Provides diagnostic feedback for fault conditions, simplifying system monitoring.
• Simplified Drive: 1:1 input-to-output ratio and On/Off interface reduce external circuitry complexity.
• Robust Packaging: D2PAK (TO-263) offers excellent thermal performance for high-power applications.
• Compliance: ROHS3 and REACH compliant, with MSL 3 (168 hours) moisture sensitivity.

VNB35N07 Applications

• Automotive Systems: Ideal for load drivers in lighting, solenoids, or motor control due to its high current and fault tolerance.
• Industrial Power Management: Suitable for relay replacements or DC motor drives where low Rds(on) and protection features are critical.
• Consumer Electronics: Used in high-current switching circuits for appliances or power tools.
• Legacy Designs: Despite obsolescence, it remains a fit for maintenance or spare part sourcing in existing systems.

Conclusion of VNB35N07

The VNB35N07 excels in high-current, low-side switching with its low Rds(on), integrated protections, and rugged D2PAK package. While obsolete, its VIPower™ technology and diagnostic capabilities make it a dependable choice for automotive, industrial, and high-power consumer applications. Designers should evaluate alternatives for new projects but can leverage this IC’s proven performance in legacy or cost-sensitive implementations.
