Infineon BTS6143D SIPMOS High-Side Power Load Switch, 38V 75A, TO-252-5
Infineon BTS6143D automotive-grade high-side power switch. 38V, 75A with full protection suite. AEC-Q100 qualified for robust applications.
The Infineon BTS6143D is a robust high-side power switch utilising advanced SIPMOS technology, designed to provide intelligent control and comprehensive protection for demanding applications. It features an integrated vertical power FET and is positioned between the power supply and the load for precise application management.
This component delivers a suite of embedded protection features for enhanced system reliability. These include short-circuit protection with latch, overload protection, and current limitation to prevent damage under fault conditions. It also offers thermal shutdown with automatic restart, overvoltage protection, and safeguards against loss of ground or supply voltage (Vbb).
Engineered for efficiency, the switch boasts a very low standby current and supports fast demagnetising of inductive loads. It provides robust electrostatic discharge (ESD) protection and is optimised for static electromagnetic compatibility (EMC). Capable of operating on 12V or 24V systems, this single-channel switch is a versatile solution for managing high-current paths.
