TVS stands for transient voltage suppressor. These devices are used to absorb and dissipate transients and over-voltage on power and communication lines. The NC350SN1T1G is an example of a TVS that uses both uni- and bi-directional symmetrical protection on both positive and negative power line surfaces. This device is built from two main components: an N-channel MOSFET and a uni- or bi-directional TVS. Together, these two components provide reliable protection against electrostatic discharge (ESD) up to 20kV (contact) and 25kV (air). In addition, this device also provides protection from over-voltage transients.

The NC P346SN1T1G offers protection against both transient over-voltage and ESD events. This device works by generating a positive feedback path across its two main components to help dissipate lightning strikes, ESD events, power surges and other over-voltage transients. Whenever an over-voltage surge occurs, the N-channel MOSFET turns on and conducts electrons from the supply line to the TVS diode. The diode then absorbs and dissipates the excess energy and then resets itself when the over-voltage surge is gone. This device also features an integrated protective Zener diode which helps limit the maximum voltage at the supply line.

The NC P346SN1T1G is widely used in consumer electronics, automotive, industrial, medical, and other sensitive application fields. This device is available in multiple packages such as D2PAK, DPAK, SMD, and SOIC. Since this device has both positive and negative power line surfaces, it provides enhanced protection for voltage levels that can exceed the absolute maximum ratings. In addition, this device has a wide operating temperature range from -40°C to 150°C.

The NC P346SN1T1G is ideal for applications that require protection from multiple sources of over-voltage or ESD events. This device uses its integrated N-channel MOSFET and uni- or bi-directional TVS diode to provide reliable protection against transient over-voltage and ESD events. It also features an integrated Zener diode which helps limit the maximum voltage at the supply line. This device is available in multiple packages and offers a wide operating temperature range, making it an ideal choice for a wide range of applications.
