TVS (transient voltage suppression) diodes, such as the 5KP130A-E3/73, are typically used in circuit boards to divert, or suppress, electrical transients or surges. These types of surges can be caused from many sources, namely spikes, lightning and electrostatic discharge (ESD); as such, TVS diodes offer a reliable protection from these and other transient voltage sources. In the following article, we will discuss the application field and working principle of the 5KP130A-E3/73.

The 5KP130A-E3/73 is an extremely fast acting TVS (diode) suitable for any application requiring transient voltage protection. This is due to the fact that it is constructed of a silicon avalanche diode which offers the optimum speed and capacitance for fast transient protection (clamping). The main application of the 5KP130A-E3/73 is in the protection of almost any system which is sensitive to electrical transients, such as computer networks, power supplies, and point-of-sale systems.

The 5KP130A-E3/73 works on an avalanching principle, meaning that it amplifies any surcharge on its input voltage and then releases it out to ground. This is achieved by having two capacitors connected in parallel, one of which is oriented in reverse and the other in forward direction. The capacitors are then connected to two diodes which form a diode bridge configuration. As the voltage at the input increases, the capacitor in reverse direction will be charged, and will eventually create a breakdown voltage when it reaches a certain threshold. At this point, the reversed biased capacitor will act as a voltage clamp and restrict the voltage from further increasing.

The 5KP130A-E3/73 is an ideal solution for protection against electrical transients. It is capable of supporting frequencies up to 2000MHz, and it has a peak pulse power rating of 178A @ 8/20us (Unidirectional only). It can also withstand reverse ESD voltages of up to 10KV (contact discharge), and has a maximum clamping voltage of 400V (Ipp=100A). Additionally, it has an independently tested and verified breakdown voltage (BV) of 8V for UL/EN 60950-1.

In conclusion, the 5KP130A-E3/73 series is a great choice for any application that requires fast transient protection. It is capable of providing reliable protection from ESD and can withstand a wide range of voltages, making it a suitable solution for powering sensitive electronic systems. Furthermore, the 5KP130A-E3/73 has a wide range of value and is UL/EN 60950-1 approved, making it an ideal choice for many different applications.
