TVS - Diodes

TVS diodes are widely used in various field of electronics, such as computers, telecom, home appliances, automotive, military and industrial field etc. TVS diodes, short for Transient Voltage Suppression diodes, are used to absorb and dissipate transient surge voltages caused by lightning stroke or switching of electronic equipment.

5KP45 Application Field

5KP45 is one of the most common type of TVS diodes. It has high current capability, excellent clamping performance and very fast response time, meeting the stringent requirements of today’s electronic industry. 5KP45 TVS diode is mostly used in military and aerospace applications because of its high surge capability and fast response time. It is also used in computers, telecom, automotive, and consumer electronics etc.

5KP45 Working Principle

5KP45 TVS diode works by providing a low impedance path to ground for overvoltage transient current. When an overvoltage occurs, the breakdown voltage of the diode is exceeded and the diode startsconducting, thus limiting the overvoltage surge and protecting the components in the circuit.In order to provide an efficient protection solution, 5KP45 TVS diode has a varistor like construction, including a metal oxide layer which improves the breakdown voltage and absorption capacity of the diode significantly. This feature allows the diode to have an extremely fast response time, even in the case of high frequency surges, and to dissipate the surge without much energy loss. 5KP45 TVS diodes also provide robust and reliable protection from surges by utilizing a surge current rating of up to 500A for 8/20 microsecond waveforms, and a voltage clamping voltage of ±70 volts for 10/1000 microsecond waveforms. This provides a good protection against high power surges such as those caused by lightning.

Conclusion

5KP45 TVS diodes are widely used in many applications such as military and aerospace, computers, telecom, automotive and consumer electronics. They provide an efficient protection solution for transient surges and offer a robust and reliable protection at the same time. It has a fast response time,Varistor-like construction, high surge current rating and a voltage clamping voltage of ±70 volts.
