PESD3V3V4UW,115

TVS - Diodes are devices that protect sensitive electronic equipment from damage caused by electrical transients, surges or spike. PESD3V3V4UW,115 is one of them with a wide application field and working principle.

Each TVS - Diode has a peak pulse energy and voltage clamping voltage which are typically specified in datasheets. The datasheet of PESD3V3V4UW,115 can be found easily online. The peak pulse energy this particular device can handle is 12.3A with a peak pulse voltage of 350V while the breakdown voltage is 5.2 V. This means that the maximum voltage level it can handle without damaging the electronic equipment is 5.2V. As such, PESD3V3V4UW,115 is often used to protect voltage sensitive components, connected to the power supply, from unexpected high or sudden voltage increases.

The working principle of PESD3V3V4UW,115 is based on the principle of avalanche breakdown. It’s a process where, when a certain threshold voltage is reached, the electric field inside the diode makes electrons to move from its valence band to its conduction band. This is due to the abrupt decrease in the resistance of the diode, which causes an abrupt increment of the current passing through it that permits high voltage to flow through without damaging the electronic component.

When an overload occurs, the TVS - Diode withstands and absorbs most of the energy but not completely. Thus, when a transient line is connected to the diode, positive and negative peaks are seen on the terminal line of the diode. Also, the diode has to have the capability to dissipate the excess energy absorbed and thus the thermal impedance of the diode is also very critical as high thermal impedance can cause excessive power to accumulate and thus cause permanent damage.

PESD3V3V4UW,115 has excellent uniformity and avalanche clamping performance with wide temperature range which makes them suitable for automotive applications. As its operating temperature range goes from -55°C to +150°C, it is used in many applications like tablet PCs, e-books, power supply modules for consumer electronics, PCs, and more. In addition, their capability to help in power supply noise cleaning makes them suitable for automotive applications as they reduce the EMI (Electromagnetic Interference) emitted from the power source and thus protect the system from external interference.

Due to its wide range of features and capabilities, PESD3V3V4UW,115 is a great component for protecting against transient voltages. It can easily be adapted to your system’s operating voltage and temperature range to give maximum protection against transient voltage events. Therefore, PESD3V3V4UW,115 can greatly reduce the risk of exposing your system to such potential damages.
