TVS - Diodes

Transient Voltage Suppressors (TVS) Diodes are designed to protect sensitive electronic devices from high level transient voltages. They are primarily used in electrical systems where power transients can cause serious malfunctions, such as in automobiles, telecommunications, computer peripherals, and consumer electronics systems. TVS Diodes are also used in industrial and military applications where power transients may endanger the lives of personnel or cause the destruction of expensive equipment.

The 3KASMC33AHM3_A/I TVS diode is an avalanche voltage suppressor (AVS) particularly designed for negative transient voltage protection. It features a high reverse breakdown voltage (VRWM) of 10V, a low leakage current (IR) of 7.5 mA, a low capacitance (CF), and a low dynamic resistance (RDYN) of 0.8 ohms. All these features make it suitable for High Input impedance application, such as LCD TV and Tablet PC.

The working principle of the 3KASMC33AHM3_A/I TVS diode is based on an avalanche breakdown mechanism. It works by providing a dynamic voltage clamping action which limits the amount of transient voltage that can be applied to a protected device. When a positive or negative transient voltage is applied to the diode, the diode\'s junction breaks down and its leakage current and dynamic resistance increase. This increase in current and voltage dissipates the transient energy and prevents it from reaching the protected device.

In order to ensure that the diode functions properly, it is important to select the correct reverse breakdown voltage, capacitance, and dynamic resistance values for the application. Similarly, it is important to consider the power and EMI requirements for the particular application in order to select a TVS diode that can handle the expected transient energy without being damaged or triggering additional sources of EMI.

The 3KASMC33AHM3_A/I TVS diode is a versatile device that can be used in a variety of different applications. It is ideal for protecting sensitive electronic devices from voltage transients in automotive, telecommunications, consumer electronics, and industrial systems. In addition, the diode\'s low capacitance and low Dynamic resistance make it suitable for LCD TV/Tablet PC displays and other high input impedance applications.
