Introduction

TVS - Diodes, also known as transil, transient suppressor, or clamp diode, is a special kind of diode used to safeguard circuits against overvoltage transients caused by electrostatic discharge (ESD), inductive switching events, and other phenomena related to loaded voltage spikes. The 1KSMB47C is a unidirectional TVS diode that is designed to protect vulnerable low voltage systems from ESD, static discharges, and electrical noise generated by inductive switching events. This article will discuss the application fields of the 1KSMB47C and its working principle.

Application Fields of 1KSMB47C

The 1KSMB47C is most often used in high-tech applications because of its fast polarity switching time and bidirectional protection features. It offers ESD protection for personal computers, office equipment, computers, medical device, telecommunications equipment, and automotive applications. In addition, it is also suitable for surge and reverse polarity protection and data line clamping. In automotive applications, automotive grade 1KSMB47C TVS diode is widely used for protecting the automated driver assistance systems (ADAS), as well as the CAN, LIN, and FlexRay buses. The TVS diode offers excellent suppression of the electrical disturbances from the automotive environment such as from engine noise, alternator spikes, and other power supply related disturbances.

Working Principle of 1KSMB47C

The 1KSMB47C TVS diode works by creating an avalanche breakdown when exposed to high voltage transients. This breakdown causes a reaction in which a coincident heavy flow of current transfers from the anode to the cathode. The heavy flow of the diode’s current returns to its original state when the transient is removed.The 1KSMB47C is also designed to provide fast recovery time. This implies that the protection is not provided continuously, but only when required. This helps to ensure that the protected system is not exposed to excessive current during normal operating conditions. The 1KSMB47C is a low-leakage and low-loss diode. It also has low leakage and low losses thus ensuring longer life and improved performance of the protected system. As a result, it provides superior protection for low voltage electronics such as computers and home appliances.

Conclusion

The 1KSMB47C is a unidirectional TVS diode designed for protecting low voltage systems from ESD, static discharges, and electrical noise generated by inductive switching events. It is widely used for protecting personal computers, office equipment, medical devices, telecommunications and automotive applications. It works by creating avalanche breakdown when exposed to high voltage transients and has a fast recovery time. The 1KSMB47C is a low-leakage and low-loss diode offering superior protection for low voltage electronics.
