TVS - Diodes have been around for quite some time, providing protection to many different types of devices. The SLD12U-017 surge protection device is one of a variety of TVS-diodes available on the market today. This device is specifically designed to protect AC/DC current and voltage sources from the effects of lightning, surges, and other high voltage events.

The working principle of the SLD12U-017 TVS diode is based on the concept of a Zener diode. A Zener diode consists of a junction between two largely N-type regions, with a small amount of the P-type material in between them. This creates an area of resistance, where, when a voltage greater than the breakdown voltage is applied, the circuit is effectively short circuited, and the excess voltage is diverted away from the equipment.

The SLD12U-017 uses a combination of two distinct Zener diodes merged into a single component. The first diode works as a positive peak clamp. Under normal operation, it will clamp the peak voltage to a predetermined limit. This limit protects the device from overvoltage issues. The second diode is a negative peak clamp. It will protect the device from excessively low voltage sources.

SLD12U-017 TVS-diodes are designed for use in a variety of potential applications, such as AC/DC power supplies, power converters, lightning protection, and automotive applications. Due to their robust design, SLD12U-017 TVS-diodes can withstand surges of up to 30,000 Amps (8/20 microseconds), making them extremely effective for protecting equipment from transient overvoltage. They are designed to automatically reset after a surge event, allowing them to be used in a variety of short and long term applications.

SLD12U-017 TVS-diodes are ideal for use in any application where protection from transient overvoltages is necessary. They are well-suited for both AC/DC and low voltage applications, as their design enables them to effectively divert away excessive voltages in both scenarios. Furthermore, their ability to withstand large surges and automatically reset makes them ideal for use in both long and short term applications, making them an excellent choice for surge protection solutions.
