PTVS5V0P1UTP,115 Circuit Protection

TVS - diodes, also known as transient voltage suppressors, provide protection for electronic circuits from undesired voltage spikes or transients; such as electrical overstress (EOS), electrostatic or lightning discharges. PTVS5V0P1UTP,115 is a high-quality transient voltage suppressor equipped with an Uni-directional, qualified 5.0V Voltage Stand-off and a 1.15A (8/20μs) surge rating. The main application fields of this device involve telecommunications systems such as ethernet, xDSL cable systems, power over ethernet (PoE), HUBs and switches.

TVS diodes are constructed from two semiconductor diodes placed back to back as shown in the figure below. This configuration acts as a bi-directional switch which is open when the voltage on the diode is lower than the breakdown voltage, but when the applied voltage exceeds the breakdown voltage, electrons from the n side are shifted into the p side of the device. This creates a high-impedance path between the two sides and charges are blocked from flowing through the diode. As a result, the voltage is clamped to a level below the breakdown voltage.

In the PTVS5V0P1UTP,115, the breakdown voltage is 5.0V, the voltage clamp (Vd) is 41.81V max, the maximum peak pulse power (tp) is 414 W, and the surge current rating (Ipp) is 1.15A (8/20μs).The TVS also includes two temperature ranges: the “A” range which is for industrial (12V-19V) and automotive (14V-40V) applications, and the “F” range which has a 0.1 Ω series-wound resistor to ensure stability and protect against permanent, irreversible damage due to power surges.

The PTVS5V0P1UTP,115 is also equipped with surge protection against transients in both positive and negative directions, and it meets all the required safety standards, including UL, FCC and RoHS. Its reliability and performance make it suitable for applications such as protection for a variety of circuit designs in telecommunications equipment, consumer electronics, automotive systems, and other high-end applications.
