TVS - Diodes

A TVS (Transient Voltage Suppression) diode is an electrical device that has the ability to protect against over voltage and transient voltage conditions and is used in many applications. The device works by quickly reacting when a voltage above its breakdown voltage is applied, allowing a relatively low current to flow through the diode to prevent damage to the protected equipment. The 5KP70A-E3/73 is a TVS diode, which has been designed for ESD protection with its fast clamping response.

Application Field and Working Principle

The main application field of the 5KP70A-E3/73 TVS diode is the protection of electrical and electronic equipment from Electro-Static Discharge (ESD) caused by electrical discharges from nearby machines or static electricity. In this type of situation, the diode acts like a clamp, clamping the voltage at a certain level (breakdown voltage) and conducting current in the opposite direction to the source, thus preventing damage to the equipment.

The TVS Diode works on the principle of PN junction diode. It consists of a reverse biased P-N junction diode, which undergoes avalanche breakdown when an excessive voltage is applied. This breakdown triggers the diode to conduct heavily, which in turn reduces the voltage to the desired level. This is done in a highly efficient manner, thus preventing the equipment from damage due to over-voltage.

The 5KP70A-E3/73 diode is specifically designed for ESD (Electro-Static Discharge) protection. It can absorb ESD transients up to ± 20kV without any performance degradation or short-circuiting the protected equipment. This makes it one of the best solutions for ESD protection in many applications. The diode also features very fast clamping response, which helps in prevention of high amplitude transients.

In addition to ESD protection, the 5KP70A-E3/73 TVS diode can also be used for protection against other voltage transients, including inductive switching events, voltage surges due to lightning and even power supply surges and glitches. In many applications, this diode is used in conjunction with other components to provide maximum protection to electronic equipment.
