Infineon BTS4142N Series Power Switch IC, 1.4W Power Rating, 45V Maximum Supply Voltage - BTS4142NHUMA1
This power switch IC is a high-side switching device intended for automotive electrical systems, providing controlled distribution of multiple loads from a single input. It is designed for surface-mount application and supports operation across automotive-grade temperature extremes, enabling integration into vehicle electronics where robust load switching and system-level protection are required.
Features and Benefits:
• Five independent outputs reduce external component count
• Low on-resistance of 320mΩ minimises conduction losses
• Maximum supply capability of 45V tolerates transient events
• Power handling rated at 1.4W supports moderate load dissipation
• Operating range from -40 to 125°C suits harsh environments
• Four-pin SOT-223 package allows compact surface mounting
• Low on-resistance of 320mΩ minimises conduction losses
• Maximum supply capability of 45V tolerates transient events
• Power handling rated at 1.4W supports moderate load dissipation
• Operating range from -40 to 125°C suits harsh environments
• Four-pin SOT-223 package allows compact surface mounting
Applications
• Suitable for switching multiple lighting circuits in vehicles
• Ideal for controlling accessory loads in body electronics
• Used with fused power rails in distributed power architectures
• Can be used for intermittent motor or actuator control
• Suitable for integration into centralised power distribution modules

What package footprint is required for board layout?
A SOT-223 four-pin footprint with surface-mount pads and appropriate thermal vias is required to accommodate soldering and heat dissipation.
How does the device cope with short-duration voltage spikes?
It is specified for a maximum supply capability up to 45V, allowing it to withstand typical automotive transient overvoltage events within that limit.
What input and output pairing does it provide?
The device accepts a single input and distributes it to five separate outputs, enabling centralised control from one supply source.
What thermal conditions should be considered during design?
The component is rated for operation from -40 to 125°C, so board placement and cooling strategies should account for ambient extremes and the 1.4W dissipation.
