VND5E050AJTR-E

VND5E050AJTR-E Description

The VND5E050AJTR-E is a high-side power switch from STMicroelectronics' VIPower™ series, designed for robust power distribution and load driving applications. This dual-channel N-channel MOSFET device integrates two independent high-side switches with a 1:1 input-to-output ratio, supporting load voltages from 4.5V to 28V and delivering up to 19A per channel. Its surface-mount PowerSSO-12 package ensures compact PCB integration, while its 50mΩ (max) Rds(on) minimizes conduction losses, enhancing efficiency. Though marked as obsolete, it remains a reliable choice for legacy designs requiring high-current switching with advanced protection features.

VND5E050AJTR-E Features

• High-Side Configuration: Enables direct control of loads without additional circuitry.
• Integrated Protections: Includes fixed current limiting, open-load detection, over-temperature, and over-voltage shutdown for system safety.
• Auto-Restart Function: Automatically recovers from fault conditions, reducing downtime.
• Low Power Dissipation: Optimized 50mΩ Rds(on) reduces heat generation under high loads.
• Wide Voltage Range: Supports 4.5V–28V loads, suitable for automotive and industrial environments.
• RoHS3 & REACH Compliant: Meets environmental standards for hazardous substance restrictions.

VND5E050AJTR-E Applications

• Automotive Systems: Ideal for ECUs, lighting modules, and motor drives due to ruggedness and fault tolerance.
• Industrial Load Switching: Powers solenoids, actuators, and PLCs with high reliability.
• Power Distribution Units (PDUs): Efficiently manages multi-channel loads in telecom/server racks.
• Legacy Equipment Maintenance: Suitable for servicing older designs requiring high-current, protected switches.

Conclusion of VND5E050AJTR-E

The VND5E050AJTR-E excels in high-current switching applications with its dual-channel design, robust protections, and low Rds(on). While obsolete, its VIPower™ technology ensures performance in demanding environments like automotive and industrial systems. Engineers seeking a compact, high-efficiency switch with integrated diagnostics may find this device advantageous for legacy or niche applications.
