TVS - Diodes

Transient Voltage Suppressor (TVS) diodes are one of the most important safety components in the electronics industry. TVS diodes act as a switch to protect devices from excessive voltages caused by ESD, electrostatic discharges and other electrical transients. The DFLT9V0A-7 is a high performance, low profile unidirectional TVS diode designed to protect high frequency electronic circuits against damage due to ESD, electrical fast transients (EFT), and lightning-induced surge transients.

Application Field

The DFLT9V0A-7 is widely used for ESD and EFT protection of data lines, as well as over-voltage protection of high frequency data and signal lines. It is suitable for Automotive, Telecom, and Consumer Electronics applications including GPS systems, tablets, and smart phones.The DFLT9V0A-7 is an optimized TVS diode which combines an extremely low capacitance of 4.5 pF with a fast clamping response. When triggered, its ultra low leakage current helps reduce the time required to complete tasks and increase system efficiency. The device also features compact form factor of 0.4mm x 0.4mm.

Working Principle

The DFLT9V0A-7 works in conjunction with an external series inductor, to create a low-impedance path for current to flow through during overvoltage transients or ESD events. When the device is triggered, the inductor, in concert with the internal diode, provides the necessary clamping voltage needed for a protective circuit while limiting the current to protect the application components.The DFLT9V0A-7 is an extremely effective over-voltage and ESD protection device, with a fast response time of less than 0.1μs. The device also works as an EMC filter to suppress electro-magnetic interference. It operates over a wide temperature range of -40°C to +125°C and is available in both uni- and bi-directional configurations.

Conclusion

The DFLT9V0A-7 is an ideal solution for ESD and EFT protection of high speed data lines. The device\'s extremely low capacitance and fast clamping response make it an attractive choice for applications where high voltage protection is essential. Its ease of use and small form factor make it an attractive choice for a variety of automotive, telecom, and consumer electronics applications.
