TVS - Diodes

A Transient Voltage Suppressor (TVS) is a type of diode used to protect components from voltage spikes and short circuits. The SMB10J18CAHM4G is an example of a TVS diode. It is designed to protect electronics from voltage transients up to 18 volts.

Application Fields

TVS diodes are commonly used in automotive, industrial, communications, and consumer electronic applications. They can be used to protect components from voltage spikes, overvoltage, and transient overvoltage conditions. The SMB10J18CAHM4G is used in general-purpose protection applications up to 18 volts and is ideal for protecting low power circuits and automotive circuits from transients. It has a low clamping voltage (11.4 volts at 1.2A) and is ideal for protecting sensitive components in a variety of applications.

Working Principle

The SMB10J18CAHM4G combines the properties of a diode with internal circuitry to detect a configured overvoltage threshold. When a voltage transient is encountered, the diode turns on and shunts the excess current away from sensitive components. The voltage is then slowly returned to its original state. Since it is designed for use in low-power applications, the clamping voltage and peak power dissipation is kept low.

The SMB10J18CAHM4G is designed to have a low capacitance, so it can quickly turn on and off to shunt the excess current away. It has low signal distortion, making it ideal for use in communication lines. It is lead (Pb)-free and compliant to RoHS standards, making it a good option for use in environmentally friendly applications.
