5KP130A-E3/54

TVS-diodes, or Transient Voltage Suppressors, are components designed to protect other circuits from overvoltage events that cause high current and unwanted operation of circuits. The 5KP130A-E3/54 is a bidirectional unidirectional overvoltage protection diode designed to protect vulnerable systems from short-duration voltage transients that may cause catastrophic failure.

The 5KP130A-E3/54 device is designed as a “unidirectional” protector, meaning that it suppresses only certain voltage transients falling in the specified voltage range. This particular device can protect across a wide array of applications, ranging from 5KV peak to 13KV peak, with a nominal 23 Amp current rating at 8/20 microseconds. The absolute maximum rating of this device is 30 Amps peak.

5KP130A-E3/54 can be used in a wide variety of applications such as motor controls, power supplies, printed circuit boards, data lines, transient voltage suppression, high power DC-DC converters, automotive components, and military/aerospace systems.

The device consists of two components; a metal oxide varistor (MOV) and a multilayer ceramic capacitor (MLCC). The MOV is an active component with the primary current and voltage limiting. The MLCC is used for EMI/RFI noise suppression. The primary function of the 5KP130A-E3/54 is to react quickly to transient overvoltages, absorbing the surge energy and dissipating it as heat. This reaction reduces the size and number of components required in an overvoltage protection solution.

In terms of working principle, the main function of the 5KP130A-E3/54 is to protect vulnerable loads from catastrophic damage from large current pulses. When a large current pulse is present, the device will respond quickly - within nanoseconds - to absorb the large current pulse, sharply limiting its rise time and clamping the voltage. This will limit the duration and amount of energy and current flowing to the vulnerable load. The device is designed to auto recover, once the transient event has passed.

The 5KP130A-E3/54 provides high quality overvoltage protection and is suitable for a wide array of applications thanks to its high surge capability rating. It offers superior performance when compared to other TVS diode devices due to its combination of both MOV and MLCC components, making it a good choice for protection from transient voltage events.
