Transient voltage suppressors (TVS) are semiconductor devices that function to protect sensitive structures in electronic circuits from high voltage, or other electrical disturbances. TVS diodes provide protection from surges, electromagnetic interference, and electrical over stress, and have been designed for use within system level circuit protection, providing effective protection to downstream components from overvoltage and other harmful electrical transients.

The CD214L-T130ALF is a TVS diode from Vishay Semiconductor, capable of providing protection from static electricity and a variety of electrical disturbances. It provides an excellent level of protection in a low-power, ultra small package, making it suitable for a number of applications.

Application Field

The CD214L-T130ALF is a 3-pin SOT-23 package, with an IEC electrical rating of 400W peak pulse to ground and 400W ESD protection. It is fully compliant with industry requirements and is suitable for use in applications such as computer and consumer electronics, communications, industrial and automotive markets.

The unidirectional CD214L-T130ALF TVS is designed to protect against lightning and other overvoltage events. It has a positive clamped voltage of 14V with a breakdown voltage of 5.0V, and a capacitance of 2.0pF. It provides superior performance and reliable overvoltage protection, eliminating the need for voltage regulation.

The CD214L-T130ALF TVS diode is capable of withstanding a number of transients, including but not limited to ESD (static electricity) and EFT (electrical fast transients). Its low capacitance makes it suitable for use in systems with high speed data communications. It also features an ultra small size, which makes it an ideal solution in space constrained applications.

Working Principle

The CD214L-T130ALF TVS diode is designed to provide protection from high voltage strikes and transients, such as lightning and electrostatic discharge (ESD). It is based on a multilayer technology, which ensures fast switching times and high surge current handling capabilities.

When the voltage across the diode exceeds the breakdown voltage specifically designed for it, the current is clamped and the diode becomes a very low resistance conductor. The TVS diode subsequently discharges the excess energy to ground, and absorbs the transient energy without affecting the normal operation of the protected component.

The TVS diode is also designed to protect against high frequency transients, such as EMI/RFI noise. It has low capacitance which minimizes the velocity of signal propagation, and wide operating temperature range from -55°C to +125°C. This makes it ideal for use in applications requiring robust protection against transients and EMI/RFI noise.

Conclusion

The CD214L-T130ALF TVS diode is an excellent solution for providing robust protection in a wide variety of applications. It is suitable for use in high voltage and transient protection applications, as well as for EMI/RFI noise protection. It also features a small size package, making it suitable for use in space-constrained applications. The CD214L-T130ALF is an economical and reliable solution for providing ESD and EFT protection.
