Transient Voltage Suppressors (TVSs) are semiconductors designed to help protect electrical and electronic systems and components from transient voltage events. Diodes, in particular, are designed to suppress the occurrence of overvoltage transients and limit the surge current. MAP4KE13A is one such diode designed for transient voltage protection applications. This article will discuss the application field and working principle of the device.

The MAP4KE13A is used in a variety of applications, including telecommunications equipment, computer data systems, consumer electronics, motor drives, electric power systems, and automotive electronics. It is especially well-suited for protecting against extreme over-voltage transients that can occur due to lightning strikes, power line surges, and electrostatic discharge (ESD). The device provides a high level of protection for systems and components by delivering a quick and reliable response to transients in the few nanoseconds following the event.

The MAP4KE13A is a unidirectional device designed to suppress voltage transients. It consists of a PN junction with a suppression line connected between the anode (positive voltage) and the cathode (negative voltage). When a transient event occurs, the voltage on the anode increases rapidly, causing a large current to flow through the line and thereby dissipating the energy of the transient. This results in a reduction of the transient voltage amplitude below the breakdown voltage of the device. As a result, the device is able to protect the system or component from harm.

When a large voltage transient appears at the anode, it causes a large current to flow through the suppression line. This current flows through a diffusion resistor that is intrinsic to the PN junction and it produces a voltage drop across the diffusion resistor. This voltage drop causes a secondary breakdown in the PN junction, resulting in full conduction and full dissipation of the energy. Once the energy has been dissipated, the device returns to its normal state with the PN junction in forward current mode.

The MAP4KE13A is designed to operate up to surge peak pulse power of 400W and a peak pulse current of 8A. It has a standing voltage of 13V and has a response time of 0.5ns. The device also has an excellent failure rate and the ability to withstand multiple transitory events. The device is robust and reliable and is designed to withstand extreme equipment dielectric stress.

In conclusion, the MAP4KE13A is an excellent choice for use in transient voltage protection applications. Its design and capabilities make it ideal for a variety of uses, including telecommunications equipment, computer data systems, consumer electronics, motor drives, electric power systems, and automotive electronics. The device has an excellent failure rate and the ability to withstand multiple transitory events. The MAP4KE13A is a reliable and robust device that provides excellent protection for systems and components.
