TVS (Transient Voltage Suppressor) Diodes are a type of protection circuit which is primarily used to protect against harmful ESD (electrostatic discharge) events and electrical transients. The 3KP28A-B is an example of a TVS diode used to protect electrical and electronic equipment from overvoltages and transients.The 3KP28A-B is a unidirectional TVS diode designed to protect circuits from fast transients caused by ESD events. It is rated for a maximum peak pulse power of 28A (8/20 μs). This diode offers a low-capacitance (13pF at 1.5kV) which makes it suitable for applications that require high-speed data lines. The device also features a low dynamic resistance and an operating temperature range of -55ºC to +125ºC.The 3KP28A-B diode is designed for use in a variety of different application fields such as telecommunications, automotive electronics, consumer electronics, industrial manufacturing, and military electronics. It can be used in high-speed equipment such as switches and routers, computer systems (including motherboards and peripherals) and automotive systems.In order to understand how the 3KP28A-B works, it’s important to first understand what a TVS diode is. A TVS diode is essentially a specialized diode which can withstand high surge voltages and also conduct current in both directions. These diodes are designed to protect circuits from the damaging effects of ESD events and electrical transients by rapidly conducting current away from sensitive components.The 3KP28A-B works by rapidly conducting current away from sensitive components during an ESD event. When the diode is exposed to a transient surge, it will conduct electricity in one direction only. This allows the diode’s built-in clamping element to absorb and dissipate the surge energy without damaging the protected equipment.The 3KP28A-B also has an integrated thermal shutdown mechanism which prevents the device from overheating due to excessive current flow. This feature ensures that the diode will remain operational and protect the equipment even in the event of prolonged or repeated ESD events.The 3KP28A-B is a versatile and reliable diode which is suitable for use in a variety of applications. It offers protection to sensitive electronic components from ESD events and electrical transients, ensuring that the equipment remains functional and reliable.
