Transient Voltage Suppressor (TVS) diodes are widely used in the protection of electronics from transient overvoltage. The MAP5KE120A is a TVS diode designed to protect sensitive electronics from electrical stress due to ESD, EFT and other surge events. In this article, we will take a look at the MAP5KE120A’s application field and working principle.

The MAP5KE120A is a low-capacitance diode designed for surge protection in a wide variety of applications, including consumer, industrial, automotive and military/aerospace. It is suitable for use in data, telecommunications and control circuits where high levels of ESD and EFT protection are needed. It can handle up to 120W peak pulse power, and offers a wide operating voltage range of 5V to 200V.

In terms of its working principle, the MAP5KE120A is a unidirectional diode composed of a PN junction. When a transient voltage exceeding the breakdown voltage occurs, the PN junction is activated and a large current flows through the device. This current is limited by the peak pulse current rating of the MAP5KE120A, which in turn provides protection for the circuit. During this process, the energy of the transient is dissipated in the form of heat.

The MAP5KE120A also has a fast turn-on time and low clamping voltage to ensure that surge currents are limited quickly. It is highly reliable, and can withstand up to 10A of continuous current. The package of the MAP5KE120A is designed for automatic pick-and-place assembly, and it is RoHS compliant.

In conclusion, the MAP5KE120A is a highly reliable low-capacitance diode from Bourns that provides effective ESD and EFT protection for a wide variety of applications. It is suitable for use in consumer, industrial, automotive and military/aerospace applications, and its fast turn-on time and low clamping voltage ensure that surge currents are quickly limited. RoHS compliant and easy to install, the MAP5KE120A is an excellent choice for protecting sensitive electronics from electrical stress due to ESD, EFT and other surge events.
