TVS – Diodes

TVS – Diodes, often referred to as Transient Voltage Suppression (or TVS) diodes are specialized devices that help protect electronic circuits from excessive voltage transients due to electrostatic discharge (ESD), electrical fast transients (EFT), power surge, and other lightning or power related events. TVS diodes use a more efficient, dynamic clamping mechanism that quickly shunt damaging transients away from sensitive electronic components before serious damage can occur.

SZ1SMB30CAT3G

The SZ1SMB30CAT3G is a unidirectional, bi-directional, or dual series transient voltage suppressor (TVS) diode from TE Connectivity. This semiconductor device is designed to protect electronics against transients caused by electrostatic discharge, electrical fast transients, radio frequency interference, and Lightning-Induced surge. This robust component is designed to provide good clamping and response capabilities with minimal signal distortion.

Applications

SZ1SMB30CAT3G diode is primarily used as ESD protection, EMI protection, and lightning protection in industrial applications which require robust and reliable transient protection. The device is capable of protecting devices from surge voltages up to 30V, making it an ideal solution for protecting interfaces like LVDS, USB, HDMI, DisplayPort, and other electrical signal lines from over-voltage conditions.

Working Principle

The SZ1SMB30CAT3G device uses a combination of a Zener diode and an avalanche diode in a series configuration. When a transient surge voltage is applied to the diode, the avalanche diode initially breaks down due to the increased voltage. This causes the diode to quickly conduct the surge current away from the device, dissipating it and thus protecting it from damage. Next, the Zener diode kicks in as it is biased into avalanche, helping to clamp the voltage and ensure that the device is not subjected to higher sustained voltage levels. This combination of Zener and avalanche diodes helps provide the device with superior protection.
