TVS diodes are electronic components used to protect against electrical transients in electronic circuits. A TVS diode is constructed out of a silicon junction diode and is designed to clamp an incoming voltage to a safe level in order to protect sensitive components from damage. The CM1293A-04MR is a transient voltage suppressor (TVS) diode designed to protect sensitive components and circuits during racing or heavy-duty purposes.

Application fields

The CM1293A-04MR is designed to be used in ESP motorsports applications. This diode is specially made to supplement the protection of mechanical parts, such as the engine, transmission, and cooling systems, from wide range of transient voltage spikes. The CM1293A-04MR is designed for installation in the power cables of the motor, as well as in the ground and power cables between the engine and the transmission to provide additional protection. This diode is ideal for use in applications where a high degree of noise immunity is required, such as those used in the automotive and race car industry.

Working Principle

The CM1293A-04MR is an unidirectional diode designed to suppress transients that may otherwise damage a sensitive electronic component. The diode works by dissipating a surge in voltage that is greater than the diode\'s rated maximum voltage. The diode is designed to direct the surge away from the sensitive component and allow the remaining energy of the surge to travel through the other side of the diode with minimal losses. When the surge dissipates, the diode remains in a reverse-biased state and waits for the next transient voltage.

The diode is designed to respond to the voltage surge quickly, in order to ensure that the sensitive components and circuits are not damaged. This fast response time is achieved by the diode\'s ability to quickly reverse bias and dump the excess voltage into the ground. When the surge has been dissipated, the diode then reverts back to its original state, allowing the electric current to flow normally through the protected component.

The CM1293A-04MR provides superior protection from electrical transients in motorsports and heavy-duty applications. It is designed specifically for installation in the power and ground lines between the engine and transmission, as well as in the power cables of the engine, for enhanced protection. The fast response time and robust construction of the diode make it an ideal choice for applications where protection from electrical transients is required.
