TVS-Diodes, or Transient Voltage Suppression Diodes, are a type of solid-state electronic component made up of a diode, a resistive element, and a capacitive element. This combination provides reliable protection against voltage transients (over-voltages) such as those caused by lightning, line surges, switching devices, and system malfunctions. In this article, we\'ll take a closer look at the SMC5K20A-M3/H application field and working principle.

What is SMC5K20A-M3/H?

The SMC5K20A-M3/H is a bidirectional unidirectional Transient Voltage Suppressor (TVS) that offers enhanced ESD protection with low capacitance. This device is designed to protect sensitive electronic components from over-voltage transients and static electricity. It is especially suited for digital electronics, which require higher levels of protection.

Application Field of SMC5K20A-M3/H

The SMC5K20A-M3/H is designed to protect sensitive electronic components from damage caused by electrostatic discharge, electro-magnetic pulse interference, or voltage transients due to lightning, power line surges, and system malfunctions. It can be used in a variety of applications, such as automobiles, consumer electronics, communication systems, industrial electronics, and medical equipment.

Working Principle of SMC5K20A-M3/H

The SMC5K20A-M3/H is composed of a diode, a resistive element, and a capacitive element. When the peak voltage of incoming over-voltage transients exceed the diode’s breakover voltage, the diode starts to conduct current. This starts a protection process, in which the resistive element and the capacitive element absorb the surge and clamp it down to a voltage within the operating range of the protected device.

The resistance of the resistive element and the capacitance of the capacitive element are responsible for limiting and clamping the surge voltage. The internal elements are set to ensure that the current is not over-dissipated. As a result, the protected device will be safe from destruction.

Conclusion

The SMC5K20A-M3/H is a bidirectional unidirectional Transient Voltage Suppressor, specially designed to protect sensitive electronic components from damage caused by over-voltage transients. It is made up of a diode, a resistive element, and a capacitive element, which work together to quickly clamp voltage outside the operating range of the device and prevent it from damage. With its wide range of applications, the SMC5K20A-M3/H is an invaluable component for any circuit.
