MXLUPT28E3 is a transient voltage suppressor (TVS) diode, which are designed to protect electronic components from damage induced by transient and high overvoltage, such as electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. They typically have fast response times, low power consumption, and excellent surge current ratings.

The MXLUPT28E3 is designed to protect a wide input voltage range (4.5V-28V) and is suitable for applications that require wide input protection. It is designed to provide protection against ESD spikes up to 20kV according to IEC 61000-4-2. The MXLUPT28E3 also has an IEC 61000-4-2 certificated wiping contact discharge surface.

The MXLUPT28E3 has an internal crowbar structure that will activate for any overvoltage event that is more than 10V above the breakdown voltage, thus protecting the device from damage. It also has an internal thermal protection that will thermally deactivate the device if the power consumption is excessive. The device also includes a low capacitance design, which minimizes the insertion loss when used as a transient voltage suppressor.

The MXLUPT28E3 is ideal for a variety of applications, including: power supplies, chargers and adapters, communication equipment, laptops, notebooks, tablets, and automotive electronics. These devices are especially useful in applications that require low capacitance, fast response times, and low power consumption.

The working principle of the MXLUPT28E3 is relatively simple. The device operates in avalanche breakdown mode, which is a phenomenon in which a current appears in the junction of two dissimilar materials. This current is caused by an increasing material resistance as the junction voltage rises above the breakdown voltage of the material. In avalanche breakdown mode, the device quickly responds to any overvoltage events that occur, thus protecting the components from damage.

The MXLUPT28E3 diode is designed to provide the highest levels of protection for a wide range of applications, from sensitive electronics to high-power components. It offers quick response time, low power consumption, and excellent surge current ratings. This makes the MXLUPT28E3 an ideal choice for applications that require transient voltage suppression, such as power supplies, chargers and adapters, communication equipment, laptops, notebooks, tablets, and automotive electronics.
