TVS diodes or Transient Voltage Suppressor (TVS) diodes are an electronic component specifically designed to protect delicate semiconductor circuitry from high-voltage transients. TVS diodes are single-piece, cost-effective devices that can withstand very high peak pulse power and are extremely reliable. The 5KP28CAE3 / TR13 is a fast, unidirectional transient voltage suppressor diode designed for general purpose use. It is used to help protect circuits from power transients and ESD, particularly where high speeds, low capacitance and low power consumption are desired.

5KP28CAE3 / TR13 Application Field

The 5KP28CAE3 / TR13 is an unidirectional diode which clamps voltage to a limited level and is mainly used in applications such as telecommunications, telecommunications equipment, laptops, smartphones, and motor controls. It is also widely used in power supply circuits, signal processing lines, and consumer electronics. It is especially suitable for protection against electrostatic discharge (ESD) and other types of over-voltage transients.

5KP28CAE3 / TR13 Working Principle

The 5KP28CAE3 / TR13 operates on the principle of avalanche breakdown. It is an integrated component that consists of a pre-structured PN junction protected by an arc suppression layer. This arc suppression layer produces a field intensity to generate a self-limiting avalanche breakdown voltage below a certain threshold voltage, which in turn suppresses the voltage applied across the diode. The clamping action of the diode is achieved by the avalanche breakdown process and the resulting current flow through and around the diode. The current flow is then limited to a safe level and protects the device or circuit from the transient.

When triggered, the breakdown voltage of the TVS diode then clamps the voltage applied across it, limiting the peak voltage below the specified safe limit. The 5KP28CAE3 / TR13 is a bidirectional diode meaning it can conduct current in either direction and can tolerate voltage up to 28V. This diode is also very fast-acting and can respond to transient pulses at a rate up to 1500volts/μs.

Conclusion

TVS diodes, such as the 5KP28CAE3 / TR13, are indispensable components for the protection of delicate circuits from power transients and ESD. This component has wide application in the telecommunications sector, as well as many other areas where reliable protection of electrical systems is essential. The 5KP28CAE3 / TR13 is a fast-acting transient suppressor diode suitable for general-purpose applications. It offers effective protection against electrostatic discharge and provides a greater level of protection than other TVS diodes with low current consumption.
