Product Description
Infineon BTS4142NHUMA1 is a high side power switch IC designed for automotive and industrial electrical systems requiring robust load switching and centralized control. Packaged in a compact 4-pin SOT-223 surface-mount device, it operates with a maximum supply voltage of 45V and power rating of 1.4W.
The device features five independent outputs from a single input, effectively reducing the need for additional external circuitry. Its low on-resistance of 320mΩ helps minimize power dissipation and conduction losses, thus improving efficiency in automotive and industrial power distribution applications.
Operating reliably over a temperature range from -40°C to 125°C, the BTS4142NHUMA1 withstands harsh environments encountered in vehicle electronics and other demanding settings. This wide thermal range is critical to support lighting circuits, accessory loads, fused power rails, or intermittent motor and actuator controls.
The SOT-223 package size (6.5mm length, 3.5mm width, and 1.6mm height) enables compact board layouts, with appropriate thermal vias advised for heat dissipation during installation. Automotive-grade AEC certification confirms its suitability for use in high-reliability vehicle systems.
