TVS Diodes are used for overvoltage transient protection of electrical and electronic devices. They consist of an array of breakover diodes designed to protect against lightning-induced transients as well as those generated by nearby electric motors or high-energy pulses produced by electronic relays, thyristors, and switching power supplies. The MART100KP43CA is an example of such diodes.

The MART100KP43CA application field centers around protection of high voltage systems on grid/off-grid applications as well as power supplies and load interface applications, 15 KVDC rating making it ideal for solar applications. It is also used in automation, power & telecommunications, and motor control applications to control voltage transients and spikes, thus providing reliable protection for circuits.

In regards to its working principle, the MART100KP43CA utilizes the Zener voltage-based avalanche breakdown to activate the transistor. This is achieved by using parallel diodes which generate a predetermined voltage, triggering the avalanche breakdown to create a low impedance path for any voltage peaks. It also employs the same principle for transient voltage protection and can withstand peak surge currents of up to 4A. When a voltage transient passes through the diode, the breakdown of the diode creates a short circuit, thereby providing protection from the transient voltage.

The MART100KP43CA also uses the temperature effect in order to improve its performance. It maintains an operating temperature below its rated level thus preventing the formation of hot spots that can damage the diode or cause premature failure. This is enabled by the use of zener clamps and varistors which absorb the energy of the voltage transients and prevent them from affecting the diode.

In conclusion, the MART100KP43CA is a TVS diode designed to protect against high voltage transients and energy pulses. It utilizes the Zener voltage-based avalanche breakdown to activate the transistor, together with the temperature effect to improve its performance. This makes it ideal for high voltage systems on grid/off-grid applications, automation, power & telecommunications, and motor control applications.
