TVS - Diodes (UCLAMP0505A.TCT Application Field and Working Principle)

Transient Voltage Suppressor diode, also known as TVS diode, is a semiconductor device widely used in various electricappliances for providing protection against high surge voltages produced by lightning or other over-voltages. It helps protect sensitive electronic components and circuits from being damaged or destroyed due to high voltages. The UCLAMP0505A.TCT is among the most popular TVS diodes in the current market.

The UCLAMP0505A.TCT is designed for applications such as telecom, data and audio protection, instrumentation, industrial control, and consumer electronics. It can be used for both Types A and B modes of over-voltage protection. The diode offers an avalanche breakdown voltage of 5.5V and a low-clamping voltage of 5V. This device is suitable for applications whose maximum operating voltage does not exceed 8V.

UCLAMP0505A.TCT utilizes two oppositely charged semiconductors to form its structure. When a surge voltage greater than the breakdown voltage is applied across its terminals, it starts conducting current. This happens because of the electrophoretic arrangement of holes and electrons on the two semiconductors of this diode. In order to discharge the surge, sometimes two or more TVS diodes are assembled in series, depending upon the amount of surge protection needed.

Another important feature of UCLAMP0505A.TCT is its fast response time. It has a response time of just 3ns, which means it can withstand very fast rising surge voltages, thereby providing effective surge protection. Besides, this device features a low dynamic resistance of 25 miliohm, high power dissipation of 177 mW, and low leakage current of 0.06uA (at 1V). The TVS has an operating temperature range of -55 to +125 degrees Celsius for its flawless performance.

UCLAMP0505A.TCT provides high uptime and improved reliability, making it an ideal solution for applications which have limited internal protection circuitry such as industrial controllers or servers. This device effectively shields sensitive components of electric circuits from damage, improving the life of the device. Moreover, the diode’s SMD package helps save board space, making it applicable for various devices and applications that have less space constraints. The UCLAMP0505A.TCT is a cost-effective solution for providing reliable over-voltage protection.
