TVS - Diodes

Transient Voltage Suppression or TVS diodes are zener diodes that are formulated for the suppression of transients in electronic circuits. Transient voltage suppression or TVS diodes are also known as voltage clamping diodes, surge protective devices, and transorbs. This article provides an overview and usage information on the 5KP54AHE3/54, a widely used TVS diode.

Application Field

The most common application field for the 5KP54AHE3/54 is as an input circuit protection device in circuits that must withstand voltages generated from transients such as electrostatic discharge (ESD), lightning strikes, and electrical transients. This TVS diode can also be used in the secondary protection circuit of switching power supplies. 5KP54AHE3/54 can also be used in motor and power circuits. This TVS diode should be used as a surge limiting element in a wide variety of general purpose electronic applications.

Working Principle

The working principle of the 5KP54AHE3/54 is zener-based. When the reverse voltage reaches a certain level, the 5KP54AHE3/54 begins to breakdown and limits the amount of current that can pass across it. This results in a voltage clamping effect which prevents the circuit from being damaged by voltage surges or spikes. The 5KP54AHE3/54 has a rated voltage of 5.6V, a maximum rated voltage of 6.0V, a rated power of 500mW and a voltage clamping current of 54mA.

Conclusion

The 5KP54AHE3/54 TVS diode is a widely used and highly effective diode for the suppression of transient voltages. The unique design of the 5KP54AHE3/54 allows it to be used in a variety of applications from input circuit protection to secondary protection circuits. The 5KP54AHE3/54 belongs to the family of voltage clamping diodes or TVS diodes and its working principle is based on zener breakdown.
