TVS - Diodes

TVS diodes (transient voltage suppressor) are a type of component mainly used to protect integrated circuits (ICs) and printed circuit boards (PCBs) from damage caused by voltage or current transients. They are also known as spike suppressors, safety diodes, and avalanche suppressors. TVS diodes are usually made of silicon, but some manufacturers have recently introduced gallium nitride diodes as well.

The 5KP36HE3/54 is a type of TVS diode, intended for industrial electrical applications. It has a breakover voltage of 36V and a peak pulse power rating of 54W. This diode is composed of a positive temperature coefficient thermistor and a diode, which helps protect the device from damage due to over-voltage.

Application Field

The 5KP36HE3/54 TVS diode can be used in a variety of industrial applications. It is commonly used in switch-mode power supplies (SMPSs) and point of use (POU) applications, such as uninterruptable power supplies (UPS) and personal computers. It can also be used in automotive power supply and battery charger applications, as well as in electric and motor vehicles.

Working Principle

The 5KP36HE3/54 TVS diode works on the basis of peak power dissipation. In other words, it works by dissipating the energy associated with voltage spikes. The diode is designed to handle pulses up to 54W of power and up to 36V of breakover voltage. When the voltage across the diode is increased above the breakover voltage, the diode collapses and dissipates the energy of the pulse, thus providing voltage protection.

When the voltage returns to normal levels, the diode re-establishes the original voltage across the device, and it is ready to protect against any additional voltage spikes. It is important to note that the 5KP36HE3/54 TVS diode is a one-time device; once it has been used it should be replaced to ensure continued voltage protection.

Conclusion

The 5KP36HE3/54 TVS diode is a reliable and cost-effective solution for providing voltage protection in many industrial applications. This type of diode is designed to handle pulses up to 54W of power and up to 36V of breakover voltage. It works by dissipating the energy associated with voltage spikes and re-establishing the original voltage when the pulse subsides.
