TVS - Diodes: MART100KP75AE3 Application Field and Working Principle

TVS diodes, also known as transient voltage suppressor diodes, are designed to protect components from electrical overstress. The MART100KP75AE3 is a common TVS diode. It is a rugged, high-power, unidirectional device intended for surge protection applications. The device offers superior clamping performance and low series resistance.

Application Field

MART100KP75AE3 TVS diodes are most often used to provide protection in industrial, telecommunication, and automotive power and communication systems. It provides protection from overvoltage transients caused by surge events such as electrostatic discharge (ESD), lightning, and inductive switching. The device is capable of handling high surge current without thermal runaway.

Working Principle

The working principle of a TVS diode is based on the principle of avalanche breakdown of a reverse-biased PN junction. The diode is reverse-biased until the breakdown voltage is reached. Once this voltage is reached, the diode begins to conduct current in the reverse direction. The energy from the overvoltage is then dissipated in the form of heat through the diode, protecting the component from damage.

Specifications

The MART100KP75AE3 is rated for a maximum peak pulse current of 100A and a breakdown voltage of 7.5V. It is designed to protect circuits from up to ±40kV ESD, and up to 8/20 ?s lightning surge waveforms (ITU-T K.14/K.20). The device includes an integrated internal oxide shield to reduce capacitance and increase stability. The diode is packaged in a small surface-mount SOD 570 package and operates in temperatures ranging from -65°C to 175°C. The device also has a high surge capability and high power dissipation.

Advantages

The MART100KP75AE3 has several advantages. It has a high peak pulse current rating of 100A.
