ECLAMP2515K.TCT is a high-performance, low-capacitance protection devices known as transient voltage suppressors (TVS). This device, using an advanced mixed technology, provides the most basic form of overvoltage protection and is commonly used in place of traditional ‘clamping’ diodes. TVS are used to protect connected electronics and other components from electrical overstress (EOS), a type of uncontrolled electrical power surge.

Application Field

ECLAMP2515K.TCT protection devices can take advantage of both bipolar and unipolar technology, allowing for extremely low operating capacitance (as low as 0.5 pF) and the ability to protect circuits from transient overvoltage events with short pulse durations (as low as 200 pico-seconds). This technology is commonly used in a variety of applications such as automotive, industrial, telecommunications, military, and aerospace systems.

The ECLAMP2515K.TCT is a popular device choice for many driven systems requiring a high peak current holding capacity, such as ignition systems and solar panel systems. It provides protection against up to 5,000V peak voltage transient, with a peak current capacity up to 30kA. In addition, its low capacitance makes it extremely suitable for high-speed data lines, such as Ethernet.

Working Principle

The ECLAMP2515K.TCT protection device combines both bipolar and unipolar technologies in two parts: a high-speed unipolar thyristor avalanche diode and a bi-directional, low capacitance, ESD-protection diode array. It is configured in an industry-standard SOD-323 package. The first part, the unipolar thyristor avalanche diode, is designed to quickly turn on and switch off in the event of a voltage overswing. The second part, the bi-directional ESD-protection diode array, is designed to suppress high-frequency transients for a longer duration while still allowing low noise levels. This dual-function design allows for robust ESD protection over a wide temperature range in a variety of applications.

In response to an overvoltage transient, the thyristor avalanche diode in the ECLAMP2515K.TCT quickly turns on to clamp the voltage and prevents damage to the system. Its series of ESD-protection diodes then turn on one after the other in order to dissipate the energy due to the transient. This allows the circuit to slowly discharge the transient energy without damaging the system. The device is also configured to both forward and reverse bias to provide effective protection from both positive and negative transients.

The ECLAMP2515K.TCT is a valuable solution for providing improved EMI/RFI protection due to its low capacitance and superior dielectric properties. Its combination of bipolar and unipolar technologies enables an extremely versatile device, capable of supporting the high current demands and wide temperature range of many applications.

Conclusion

The ECLAMP2515K.TCT is a reliable and cost-effective solution for providing superior protection against electrical overstress in a variety of applications. Its advanced mixed technology offers the most comprehensive protection available with the smallest available size. Additionally, its low capacitance and ESD protection make it perfect for high-speed data lines. With its broad range of features and advantages, the ECLAMP2515K.TCT is an excellent choice for many driven systems that require robust EMI/RFI protection.
