TVS (Transient Voltage Suppressors) Diodes are elements of circuits which offer enhanced protection against over-voltage conditions, and in many cases act as the sole means of protection against high-voltage transients. The NUP2115LT1G is a diode from the NUP40x0LT series from ON Semiconductor, which provides enhanced circuit protection and reliability over a range of voltage and power levels.

In terms of application, the NUP2115LT1G is suitable for consumer electronics, notebook computers, telecommunications systems, automotive systems, and any other products where over-voltage conditions can occur. It is used in situations where the application of such technology is needed to prevent damage due to short duration, high-voltage transients.

Operation wise, the NUP2115LT1G is a unidirectional transient voltage suppressor diode. It has an operational range of 6V to 30V and can be operated up to 2 amperes. It is equipped with a conformal coated, glass n-channel transistor array, two schottky barrier diodes, and an inductive load. The diode can effectively reduce circuit damage due to over voltage conditions by clamping, limiting, and shunt-mode protection.

The diode operates in a two-step process. The process starts with the N-channel transistor array. It acts as an on-off switch which responds to over-voltage or over-current conditions. This switch activates the secondary circuit which consists of the two Schottky barrier diodes, and the inductor.

When an over-voltage or over-current occurs, the N-channel transistor array is driven by a current pulse from the primary input, forcing the second section of the device to operate. The Schottky barrier diodes provide rectification and filtering of the incoming signal. The inductor, which is powered by the Schottky diodes, functions as an energy storage unit. The stored energy is dumped into the load, allowing the over-voltage or over-current to be dissipated as heat.

The NUP2115LT1G is a highly reliable circuit protection device which can effectively suppress over-voltage and over-current conditions in circuits. It is suitable for use in consumer electronics, telecommunication systems, automotive systems, and any other product that is prone to over-voltage and overload conditions. The device is easy to install and offers excellent protection and reliability.
