TVS - Diodes

NUP2202W1T2G is an integrated transient suppressor diode which belongs to the category of TVS - Diodes.

A TVS diode is an electrostatic protection device which enables it to protect sensitive circuits from destructive voltage or current spikes. TVS diodes are also known as Transient Voltage Suppressor (TVS) devices, and they are mainly used to suppress electrical transients which are caused by electrostatic discharges, inductive loads, cable interaction and other voltage or current spikes. TVS diodes are also capable of absorbing and dissipating voltages and currents in excess of their rated values.

The structure and design of such type of TVS diodes enables them to dissipate large amounts of energy in a short period of time, while also preventing the destructive transient from reaching the protected circuit. They are also capable of conducting large amounts of current without being damaged, and they also have high power dissipation rating and very low leakage current. These features enable them to be used in various applications such as in automotive, industrial, consumer electronics, medical, laser, telecom, and military.

The NUP2202W1T2G is a unidirectional TVS diode which has a low stand-off voltage of 5.3V, fast response time of 5ns, a high ESD capability of 25kV, and a maximum peak pulse power rating of 500W. It can be operated in temperatures from -65°C to 150°C and is also UL approved.

The NUP2202W1T2G is suitable for use in a wide range of applications, including automotive, industrial, consumer electronics, LED drivers, solar panel gate drives, medical, and telecom. It provides protection for equipment from the damaging effects of electrical fast transients, which are caused by inductive loads, electrostatic discharge, and other overvoltage or overcurrent events. It is also suitable for high-power, capacitive loads, and sensitive analog circuits.

The protection principle of such a device is to allow a low current to pass when no overvoltage occurs, since the diode will be reverse biased. As soon as an overvoltage occurs, the current through the diode will be increased, leading to an avalanche breakdown and therefore effectively diverting all the current flowing through the diode. The extra current passing through the diode will be quickly dissipated as heat, and the overvoltage protection will be restored after the transient has been dissipated.

In conclusion, the NUP2202W1T2G is a reliable and robust TVS diode which provides protection from transient voltage or current spikes. It is suitable for use in automotive, industrial, consumer electronics, medical, laser, telecom, and military applications, and can be operated in temperatures from -65°C to 150°C.
