VNB20N07

VNB20N07 Description

The VNB20N07 from STMicroelectronics is a low-side power switch designed for general-purpose load driving applications. Part of the OMNIFET™ and VIPower™ series, this obsolete but robust device integrates a single N-channel MOSFET with a 1:1 input-to-output ratio, capable of handling up to 14A continuous current and 55V maximum load voltage. Packaged in a D2PAK (TO-263) surface-mount form factor, it features 50mOhm (max) Rds(on) for efficient power dissipation. The device operates without an external supply voltage, simplifying system design.

VNB20N07 Features

• Integrated Protection: Includes fixed current limiting, over-temperature shutdown, and over-voltage protection, enhancing reliability in harsh conditions.
• Status Flag: Provides fault feedback, enabling diagnostics for improved system monitoring.
• Low On-Resistance: 50mOhm (max) Rds(on) minimizes conduction losses, improving thermal performance.
• RoHS3 & REACH Compliant: Meets environmental standards, suitable for modern eco-conscious designs.
• Wide Load Voltage Range: Supports up to 55V, ideal for automotive and industrial applications.
• No Vcc/Vdd Required: Simplifies circuitry by eliminating the need for a separate driver supply.

VNB20N07 Applications

• Automotive Systems: Ideal for solenoid drivers, relay replacements, and LED lighting control due to high voltage tolerance and ruggedness.
• Industrial Load Switching: Used in motor drives, actuators, and power distribution modules where low Rds(on) and protection features are critical.
• Consumer Electronics: Suitable for high-current switching in appliances, leveraging its compact D2PAK packaging.
• Battery Management: Efficiently controls discharge paths in portable devices and energy storage systems.
