Infineon HITFET Series Power Switch IC, 3.8W Power Rating, 1.4A Operating Current - BSP76E6433HUMA1
This power switch IC is a low-side semiconductor device designed for switching and protection roles in electronic systems. It operates from a low-voltage supply and is intended for surface-mount placement on PCB assemblies where controlled low-side switching of loads is required. The component is suitable for environments demanding wide temperature tolerance and compact packaging.
Features and Benefits:
• 480mΩ Rds(on) delivers low conduction losses under load
• 10V maximum supply enables compatibility with common low-voltage systems
• 1.4A operating current supports moderate continuous load currents
• 3.8W thermal rating allows sustained power dissipation handling
• -40°C to 150°C temperature range enables high-temperature operation
• 4-pin SOT-223 surface-mount package simplifies PCB assembly
• 10V maximum supply enables compatibility with common low-voltage systems
• 1.4A operating current supports moderate continuous load currents
• 3.8W thermal rating allows sustained power dissipation handling

• Used for board-level load protection in rugged electronics
How many control inputs and switched outputs does it support?
It accepts a single control input and provides five independent switched outputs for distributing one command to multiple loads.
What mounting considerations are required for thermal performance?
Use a PCB layout with thermal land and copper pours beneath the SOT-223 pad to improve heat sinking and maintain the device within its thermal dissipation capability.
What topology does it implement and what is the functional implication?
It implements a low-side switching topology, meaning the device switches the connection of the load to ground and is best placed between the load and return path.
What pin count should designers expect when integrating it?
The package exposes four pins, which must be routed according to the schematic for input control, ground return and multiple output connections.
