TVS - Diodes, or Transient Voltage Suppression Diodes, are electronic components which are designed to protect sensitive electronic components from damage due to exposure to transient or overvoltage conditions. In today\'s electronics, these vulnerable components often include computers, mobile phones, medical and industrial devices.

The 5KP28CA-HRA-B is a TVS diode based on glass passivated junction chip technology. It is an axial-leaded, unidirectional, transient voltage suppression (TVS) device specifically designed to protect voltage sensitive components from transient overvoltage events. This component minimizes voltage overshoots and/or ringing and can offer up to 28A spike current protection.

The 5KP28CA-HRA-B is designed to protect against transients and electrostatic discharges on I/O interfaces. The standard package provides multiple protection levels for high-speed serial and parallel data lines, as well as USB and peripheral ports on computers or mobile phones. Its features make it ideal for use in industrial applications like motors, relays, automotive, automation and control systems.

The working principle of the 5KP28CA-HRA-B is based on the typical breakdown characteristics of a diode. When the voltage applied across the anode and cathode exceeds the threshold voltage, the diode undergoes a breakdown process or avalanche breakdown. This avalanche breakdown is what causes a large amount of current to flow through the diode, allowing the entire device to quickly dissipate the energy associated with a switching or ESD transient.

The 5KP28CA-HRA-B features an internal lead frame which improves heat dissipation and ESD protection. This device is offered in several voltage ratings, depending on the application, and is highly efficient in peak pulse current. It is designed with an axial lead, making it very easy to install and use in a compact space.

In summary, the 5KP28CA-HRA-B is a transient voltage suppression (TVS) diode that is used to protect sensitive electronic components from damage due to exposure to transient or overvoltage conditions. It features internal lead frame, axial lead, multiple protection levels, and is capable of providing up to 28A peak pulse current protection. This particular TVS diode works by undergoing an avalanche breakdown when the voltage applied across the anode and cathode exceeds the threshold voltage.
