The Application Field and Working Principle of SM712-TP

The SM712-TP is a type of Transil™, a transient voltage suppressor (also known as a TVS diode). It is designed to protect sensitive electronic equipment from high voltage spikes and surges, which could potentially damage the equipment. The device can also be used for low-voltage applications, such as short-circuit protection and overvoltage protection. The SM712-TP is an integrated circuit containing two separate and distinct functions, both necessary for a successful TVS application.

Application Fields

The SM712-TP is most commonly used to protect circuit boards, semiconductor components, and other sensitive electronic components from high voltage surges and spikes. It can be used to protect against electrical noise, transients, and surges due to lightning or power line events. The device can also be used in sminterruptor multi-stage protection systems as a low-voltageTVS (LTVS) device. The SM712-TP is available in a wide range of package sizes, including surface-mount and through-hole packages, which makes it suitable for a variety of applications.

Working Principle

The SM712-TP employs two distinct functions to provide effective and reliable protection from electrical disturbances. The first function is the avalanche breakdown diode, which shifts the voltage spike to a safe level and reduces the amplitude of the transient. The second function is the clamping element, which absorbs the excess energy of the transient and dissipates it as heat. The avalanche breakdown diode is a high-speed semiconductor device that acts as a short-circuit for high-voltage transient events, allowing an instantaneous voltage increase of less than 1 volt. The voltage surge is then transferred to the clamping element, which absorbs the excess energy and dissipates it as heat. This combination of avalanche breakdown and clamping elements provides highly effective and reliable protection from electrical disturbances.

Conclusion

The SM712-TP is an effective and reliable TVSdiode suitable for a wide range of applications. It is designed to provide protection from electrical disturbances due to transient and/or ESD events. The combination of avalanche breakdown and clamping elements provides excellent protection from electrical disturbances, while the range of available package sizes makes the device suitable for a variety of applications. This makes the SM712-TP an ideal choice for applications requiring protection from electrical disturbances.
