TVS - Diodes

The 1KSMB39CA M4G is a transient voltage suppressor (TVS) diode used in a variety of applications for protecting electronics from transient voltages caused by electrical surges. TVS diodes are a form of voltage-dependent, nonlinear, asymmetric, reverse-biasing diodes that respond to a wide range of transients.

TVS diodes are two-terminal solid-state devices that can be thought of as specialized zener diodes. They are connected between a circuit’s power supply and ground to protect it from transients. During normal circuit operation, the diode operates like an open switch, allowing the current to flow freely. However, when a transient spike or surge is encountered, the diode turns to a closed state, diverting the current away from the protected circuit. This protects the circuit from any damage that could be caused by the rush of current.

The 1KSMB39CA M4G is a common type of TVS diode, which is characterized by its low working voltage, low clamping voltage and low maximum leakage current of 0.1 µA. As a result, it is ideal for protecting sensitive electronic components and circuits from voltage transients caused by lightning strikes, induced static voltages, switching and motor surge currents, accidental application of power, or other external sources of disruption.

In addition to the 1KSMB39CA M4G, there are a variety of other TVS diodes available for different applications, such as automotive, industrial and general-purpose applications. Each one is designed to provide specific levels of protection depending on the application. For example, in automotive applications, TVS diodes must be able to withstand very high transient voltages caused by lightning induced static discharge, engine start-up and battery up-surges.

In summary, TVS diodes are used in a variety of applications for protecting electronics from transient voltages caused by electrical surges. The 1KSMB39CA M4G is a common type of TVS diode, which is characterized by its low working voltage, low clamping voltage and low maximum leakage current. TVS diodes are available for different applications, such as automotive, industrial and general-purpose applications, and each one is designed to provide specific levels of protection depending on the application.
