TVS (transient voltage suppressor) technology is the most reliable technique currently used to protect sensitive electronics against electrical transient voltage spikes, which are typically caused by lightning and electrostatic discharge (ESD). The SN65220YZBT is a state-of-the-art, low-loss, mixed-technology TVS product, offering maximum protection for mission-critical applications.

The SN65220YZBT combines two distinctly different technologies to provide superior protection against transient voltage surges. The first is a standard unidirectional TVS diode, which is designed to protect against ESD and high energy electrostatic events. The second component is a spark gap element which protects against high current, high energy transients, such as those caused by lightning strikes.

The SN65220YZBT has a working principle that is based on both electrical and mechanical components. The electronic part of the TVS is composed of two back-to-back diodes connected in series, which prevents current flow in either direction. The mechanical part is composed of a spark gap element, which is designed to dissipate the surge energy when it is triggered by a high voltage. The spark gap works the same way as an electrical fuse; when the voltage passes a certain threshold, the spark gap switches from its normally closed state to an open state, effectively short-circuiting the high-energy transient.

The SN65220YZBT is designed to handle higher power transients than standard TVS diodes, so it is ideal for mission-critical applications in the broadcast and telecommunications industries, where maximum protection from electrical transients is essential. It is also suitable for use in industrial environments, where it can protect components from lightning-induced transients.

The SN65220YZBT provides superior protection against power transients, while offering low power losses, making it the ideal solution for your application. With its combination of electronic and mechanical components, the SN65220YZBT provides maximum protection from both ESD and lightning-induced transients. Whatever your application, the SN65220YZBT is the perfect choice for protecting your mission-critical systems.
