TVS - Diodes, also known as Transient Voltage Suppression Diodes in short TVS-Diodes, have been quickly replacing the use of the gas discharge tubes and other types of diodes for protection against surge voltages for electrical appliances. More specifically, the TVS8151MUTBG, which is a bi-directional Unidir triggering Transient Voltage Suppressor (TVS) Diode, is designed to provide the same level of protection, but with a higher degree of starting voltage and improved transference of power. Its main purpose is to protect against over voltage in applications ranging from telecom and consumer electronics to industrial applications.

The TVS8151MUTBG offers reliable surge protection in various applications such as AC/DC adapter protection, power input/output line protection,USB 3.0/3.1/Type-C port, and laptop port protection among other things. The device is manufactured in a lead-free, space saving, SOD882-51 package which has closed view. Furthermore, it boasts of excellent clamping capability and low insertion loss. It has an operating temperature range of -40°C to +125°C and can handle maximum peak pulse power of 1500W for 10/1000 μs waveform. All these properties make it an ideal choice for ‘Real Estate’ sensitive applications.

Now, coming to its working principle, the TVS8151MUTBG is a voltage clamping device, meaning that it is designed to restrict the voltage from exceeding a certain level which is known as the ‘clamping voltage’. This device utilizes a reverse biased PN junction diode configuration to suppress high voltage surges. When the voltage exceeds the breakdown limit of the PN junction, the diode conducts current and provides a path for the surge current to flow, thus preventing damage to the connected equipment. Once the voltage drops, the diode is no longer able to conduct current and thus, the surge is stopped.

All in all, the TVS8151MUTBG is an incredibly useful device that is designed to protect connected devices from overvoltage surges. With its high degree of starting voltage and excellent transference of power, its use has become widespread in a diverse range of applications. With its protection, users can rest assured that their devices are safe from power surges.
