MART100KP70AE3

Transient Voltage Suppressor (TVS) Diodes are the energy-saving components used to protect circuits from electrostatic discharges (ESD) and voltage transients. They are widely applied in digital and analog electronics, power supplies, and military applications. MART100KP70AE3 (hereafter referred to as MART), a type of TVS-diode, is specifically designed to provide an excellent ESD supplier protection.

Application Field of MART

MART is generally applied in the operating voltage of 20V and is capable of withstanding over-voltages up to 70V. It is capable of providing protection for a wide range of electrical systems, such as automobile CAN bus, I/O ports, USB ports, and all kinds of printed circuit board (PCB). Furthermore, it is suitable for any application where the size and cost are of prime concern.

Working Principle of MART

MART, as a TVS-diode, works for a broad range of applications. In general, the MART device acts as an over-voltage protection that utilizes a special kind of structure to effectively protect circuits from high voltages. In this way, it can prevent the circuit from being damaged by unexpected voltage. In addition, it will clamp the excess voltage and dissipate the additional energy safely, infrequently providing protection in excess of a lightning strike.

When the voltage source input is greater than a specific voltage, the Avalanche breakdown phenomenon is triggered. During this event, a large number of charges are created, resulting in an increase of current. In addition, as the voltage VBR (breakdown voltage) keeps increasing, the current amplitude will further be amplified. This is the main reason why MART provides a high-level protection.

On the other hand, the MART diode is not only used as a protector against high energies, but also acts as a noise suppressor during operation. In such situation, the MART device can limit the peak current decrease so that normal operation can still proceed.

Conclusion

MART100KP70AE3 is a type of Transient Voltage Suppressor (TVS) diode, which is used to provide circuit protection from ESD and over-voltage transients. By utilizing the Avalanche breakdown phenomenon and limiting the peak current decrease, it is ideally suited for automotive CAN bus, I/O ports, USB ports, and other sensitive electronics. With its small size and low cost, MART diode is an invaluable device for a range of applications.
