TVS - Diodes
TVS diodes, also known as Transient-Voltage-Suppression diodes, are a type of semiconductor diodes that are designed to provide an extreme level of protection from Electrostatic Discharge (ESD), and other surges in electronic systems. The SZ1SMA28CAT3G is a TVS diode specifically designed for ESD protection. In this article, we will discuss the application field and the working principle behind this component.

The SZ1SMA series TVS diodes are mainly designed for ESD protection in portable electronic devices. These TVS diodes are appropriate for use in cable interface and internal circuits, such as USB 3.0, HDMI, MHL, and more. The type 3G version of the SZ1SMA28CAT3G has an ESD protection capability of up to 8kV Contact Discharge, and up to 30kV Air Gap Discharge.

The working principle behind the SZ1SMA28CAT3G is quite simple. Under normal conditions, the TVS diode is in a non-conductive state, but when a large voltage spike or surge is detected on the conducting path, the diode will quickly clamp down the voltage, protecting the sensitive components connected to it. This instantaneous clamping action is achieved by the diode structure itself. These TVS diodes possess a reverse standoff voltage, which when exceeded, will cause an avalanche breakdown of the diode junctions, allowing current to freely flow from the anode to the cathode. This clamps down the voltage quickly and protects the device.

The SZ1SMA28 CAT3G is also very reliable due to its reverse low leakage current and fast response time. Its reverse leakage current is typically less than 0.5µA at 6.5V and the response time is typically less than 1.0nS. This ensures that the SZ1SMA28CAT3G can reliably protect against large surges, while allowing normal current to flow freely.

In summary, the SZ1SMA28CAT3G is a TVS diode designed for ESD protection in portable electronic devices. This diode has an ESD protection capability of 8kV Contact Discharge and 30kV Air Gap Discharge. The working principle behind the SZ1SMA28CAT3G is that when a large voltage spike is detected, the diode will quickly clamp down the voltage, protecting the sensitive components connected to it. The diode is also reliable due to its reverse low leakage current and fast response time. Thus, the SZ1SMA28CAT3G is a great choice for ESD protection in portable electronic devices.
