ESDA14V2L is a mobile TVS (transient voltage suppressor) diode, suitable for a wide range of mobile applications. This diode is designed to suppress transient voltage surges and spikes, providing circuit protection in electronic systems. TVS diodes typically have breakdown voltages between 5V and 5kV and are available in a variety of packages including SMD and DIP.
ESDA14V2L is designed with a particular focus on unidirectional transient overvoltage protection. Its reverse standoff voltage, also known as breakdown voltage, is 14V, exceeding the 11V typical of most transient overvoltage suppressors. Its capacitance of 1.3 pF is the lowest among all TVS devices.
The primary advantage of ESDA14V2L is its low clamps range. Transient overvoltage is clamped to a value 5V below the reverse standoff voltage, which in this case is 9V. This creates a very efficient overvoltage protection. It is also designed to have a low operating voltage, typically 5V while reducing the total height to 1.2mm.
The application field of ESDA14V2L can be anywhere where transient voltages and surges are an issue. It can be used in telecommunications, automotive, computing, consumer electronics, and aerospace devices. Its working principle is based on the avalanche breakdown principle, which states that when a reverse bias voltage above certain value is applied to a diode, then the electric field in the depletion layer of the diode increases exponentially. This exponential increase in the electric field results in ionization of the immobile charge carriers and formation of free electrons and holes. This process leads to a avalanche breakdown. This process is self sustaining and results in high current flow in the diode.
When the transient voltage increases above the breakdown voltage, the current in the diode increases exponentially and is dissipated across the diode, leading to voltage clamping. This prevents the surge or spike voltage from passing through to the system, thereby protecting it. The high peak current is absorbed by the diode and is then dissipated in the form of heat. The device is able to handle reverse surge currents up to 2A and can handle surge currents up to 200A.
In summary, the ESDA14V2L is a mobile TVS diode used to protect electronic systems from transient voltage surges and spikes. It has a low typical breakdown voltage of 14V and a low clamping range of 5V. It is suitable for a wide range of applications including telecommunications, automotive, computing, consumer electronics, and aerospace. It works based on the avalanche breakdown principle and is able to handle reverse surge currents up to 2A and surge currents up to 200A.
