BTS500151TMAAKSA1

Overview

The BTS500151TMAAKSA1 is a single-channel smart high-side power switch from Infineon's Power PROFET™ family. It operates within an input voltage range of 3.2 V to 28 V and supports a continuous load current of 30 A with a short-circuit current limit of 70 A. The device features a maximum on-state resistance of 2.5 mΩ and handles up to 200 W power dissipation. It utilizes a PG-TO-220-7 package for surface mount installation, ensuring robust performance in automotive environments across temperatures from -40°C to +150°C.

Feature Summary

• Integrates diagnostic capabilities including sense load current monitoring and protection functions.
• Designed for automotive applications meeting specific quality standards.
• Provides intelligent switching with low on-state resistance for efficient power distribution.

Applications

• Automotive lighting systems
• Power distribution units in vehicles
• High-current load switching in automotive electronics

Procurement Notes

Verify the exact package type and pinout configuration against the official datasheet before integration, as variations exist within the series. Confirm that the component meets the required automotive quality standards for your specific application environment. Ensure thermal management solutions are adequate for the specified power dissipation limits during operation.

Selection Notes

Select this component when a single-channel high-side switch with integrated diagnostics and automotive qualification is required. Compare the 30 A continuous current rating and 2.5 mΩ on-resistance against system load requirements. Consider the PG-TO-220-7 package constraints for PCB layout and thermal design compared to other available packages in the same product family.

Part Context

This part belongs to the BTS50015 series of ultra-low ohmic smart high-side switches. It is distinct from surface-mount variants like the BTS50015-1TAA by its through-hole compatible PG-TO-220-7 packaging. The series is characterized by comprehensive protection features and diagnostic feedback suitable for demanding automotive electrical loads.

Replacement Considerations

Direct substitutes include other BTS50015 series variants such as BTS50015-1TAD or BTS500151TMAAKSA1 equivalents if package compatibility allows. Verify functional equivalence regarding current ratings and diagnostic outputs before substitution.
