TVS - Diodes are devices used to protect semiconductors from overvoltage transients. They are commonly found in power supplies, circuit boards and many other places where protection from voltage surge is desirable. The DE2707500L is a type of TVS - Diode developed to protect sensitive electronic components from voltage transients and power surges. The DE2707500L is a TVS - Diode located in a single, symmetrical package. It boasts a low capacitance, high breakdown voltage and low clamping voltage, making it a suitable choice for sensitive applications.

The DE2707500L’s application field is notably broad, making it a great choice for numerous board-level applications. It functions as an overvoltage suppressor and EMI filter, specifically for use in mixed-signal applications. These applications typically include AC adapters, set-top boxes, USB, Ethernet and serial interfaces. DE2707500L also provides protection from electrostatic and radio frequency fields offered by cell phones, wireless units and gaming devices.

The DE2707500L boasts a maximum working voltage of ± 27 V - very impressive for a single, symmetrical package. It is able to operate in temperatures ranging from -55 Celsius to +150 Celsius, making it very suitable for regular use in colder environments. The peak surge power rating of the DE2707500L is 6.4 watts at 10/1000μs, and the IEC61000-4-5 rating offers protection from power surges up to 200 amps.

The DE2707500L’s internal working principle is quite simple. When an overvoltage transient occurs, the DE2707500L automatically turns on and begins to conduct. As the voltage climbs, it begins to clone the load across the gap, limiting current and dissipating the excess voltage energy. The resistor inside the DE2707500L effectively reduces the voltage while resisting current, releasing heat as a result. The capacitance offered by the DE2707500L provides good protection against electrostatic and other types of interference.

To summarize, the DE2707500L appears to be an excellent choice for board-level protection against overvoltage transients. Its low capacitance, high breakdown voltage and low clamping voltage capabilities make it a suitable solution for various applications ranging from AC adapters to USB interfaces. Its peak surge rating of 6.4 watts and its IEC61000-4-5 rating of 200 amps offer effective protection from power surges. The DE2707500L’s simple internal working principle uses a resistor to reduce the voltage and dissipate the excess voltage energy. Its combined features make it a great alternative to conventional protection devices.
