TVS - Diodes

TVS diodes, also known as transil diodes, are components designed to provide protection and isolate electrical circuits from high-energy transcient pulses. The NUP2201MR6T1 is a high speed bidirectional diode which is designed to protect voltage sensitive components from voltage transients induced by minimum or maximum power line suppressing pulses, lightning, or electrostatic discharges (ESD). It is an ideal choice for transient voltage surge suppression.

The NUP2201MR6T1 has a broad application field. It can be used as a pre-conditioner in automotive applications to prevent voltage disturbances from entering the vehicles electrical system. Similarly, telecom equipment, computers and other electronic devices are also protected by these diodes against voltage transients.

The operating principle of the NUP2201MR6T1 is based on avalanche breakdown. When the voltage across the diode is higher than the breakdown voltage, which is referred to as the avalanche voltage, the diode is able to convert the high voltage spike into a harmless, lower voltage level. This process requires a reverse current, which is generated when the diode is exposed to a voltage surge.

The responsivity time of the NUP2201MR6T1 is around 10ns, meaning that the diode is able to respond to the voltage surge within a near immediate time frame. The emitted output voltage is approximately 5V below the breakdown voltage, which is an important feature when considering overvoltages from 20V to 170V. The maximum reverse current allowed by this component is 5A, while its forward current rating is 200mA.

In conclusion, the NUP2201MR6T1 is a high-speed bidirectional TVS diode designed to provide protection against transcient pulses. The large range of applications where this component can be used and its fast responsivity time make it an ideal candidate for numerous protection tasks. Its operating principle based on the avalanche breakdown and its several useful features make it highly reliable and efficient.
