5KP51-E3/54

TVS (Transient Voltage Suppressor) diodes are special type of semiconductor components used to protect electronic circuits from damage caused by electrical transients. 5KP51-E3/54 is a unidirectional television suppression (TVS) diode used for low frequency applications. It solely provides unwanted voltage protection against over-voltage events, such as electrostatic discharge (ESD), inductive switching, and lightning.

Application Field

The 5KP51-E3/54 is designed specifically for surge or transient protection applications. It is used in applications such as power supplies, TV displays, mobile phones, medical systems, and automotive electronics. It is designed to protect device against transient events such as ESD, EFT, and lightning.

Working Principle

The 5KP51-E3/54 is a unidirectional TVS diode, which means that it only blocks current from flowing in one direction. When a voltage transient hits the diode, it triggers an avalanche breakdown, allowing large amounts of current to pass through the device. This limited conduction causes a voltage drop across the diode and absorbs the energy of the transient, preventing it from reaching the device. The 5KP51-E3/54 has an ultra-low capacitance and fast response time, making it suitable for surge protection in harsh environments.

The 5KP51-E3/54 can withstand transient voltage up to 5.00kV and can absorb energy up to 1000 mJ. It has a fast switching time of around 10ns and an almost non-existent stray inductance of only 35nH. The device is able to handle continuous pulse waveforms of up to 40A (Tj 125°C) and it is UL (Underwriters Laboratories) approved.

In conclusion, the 5KP51-E3/54 is a unidirectional TVS diode designed specifically for low frequency surge or transient protection applications. It is fast responding, has an ultra-low capacitance, and can absorb high levels of energy. It can withstand voltage transients up to 5.00kV and can handle continuous pulse waveforms of up to 40A (Tj 125°C).
