TVS-Diodes such as DF5A5.6JE and LM are components that are used to protect sensitive electronics from electrical overstress (EOS) and electrostatic discharge (ESD). They accomplish this mainly by clamping voltages that exceed a given threshold.

DF5A5.6JE and LM are both avalanche breakdown type TVS-Diodes. When the TVS-Diode is exposed to a voltage that exceeds the avalanche voltage, the energy generated by the avalanche breakdown quickly increases the current flow, and the breakdown current directly exceeds the P d power of the power tube body. The greater the current, the greater the protection of the device. When the abnormal voltage disappears, the power tube will automatically return to its off state.

DF5A5.6JE is a surface mount transient voltage suppressor designed for applications that require higher levels of ESD/EOS protection. It is a unidirectional diode with low leakage current and can provide up to 15kV discharge. It features low capacitance and simple series connection can help gain even greater ESD protection. Meanwhile, LM is a dual bi-directional transient voltage suppressor and it offers improved protection for both ESD and EOS. It has high surge current capability and low leakage current. It can provide up to 20kV of clamping voltage protection and 20mA to 50mA peak pulse current.

These TVS-Diodes are widely used for protection in consumer electronics, automotive and industrial applications. For example, they can be used as overvoltage protection for audio and video devices, security systems, integrated circuit logic, and more. They are also used to protect against ESD events that can damage sensitive electronics. One other common use is to provide ESD protection on vehicle electrical systems and automotive electronics.

In summary, TVS-Diodes such as DF5A5.6JE and LM are important components used to provide protection to sensitive electronics against electrical overstress and electrostatic discharge. They mainly utilize the process of avalanche breakdown to achieve high levels of ESD/EOS protection and are used in a variety of applications including audio/video, security, automotive, and industrial systems.
