The USB50812E3/TR7 TVS Diode is a voltage transient suppressor designed to protect sensitive electronics from transient electrical surges. It is a single line, unidirectional general-purpose avalanche-style diode with fast response time and low capacitance. The device is bidirectional and features integrated ESD protection, eliminating the need for two parts—an array of discrete varistors and an ESD protection device—in one package. This device provides excellent protection against destructive, disruptive electrical transients such as ESD, lightning, and IEC61000-4-2.

The USB50812E3/TR7 is ideal for protecting against transients on sensitive electronics, such as in mobile device, automotive, and medical applications. It can also be used to protect against IEC61000-4-2 ESD surge attacks in industrial, aviation, and communications fields. The low capacitance of this device means that it can also provide excellent protection for data lines, such as USB and other sensitive transmission lines.

The working principle of the USB50812E3/TR7 is simple. When a transient voltage surge occurs on the line, the avalanche-style diode immediately turns on, dissipating the energy within the device as heat and clamping the line to a safe voltage. The integrated ESD protection device in the package protects against ESD surges and any other transient energy that might occur.

In addition to its fast response time and low capacitance, the USB50812E3/TR7 has other features that make it attractive in many applications. For example, it has an extremely low failure rate, making it ideal for high-reliability systems. It is also RoHS compliant, making it an ideal choice for applications that require compliance with various environmental regulations.

The USB50812E3/TR7 is a versatile device that can be used to protect against a variety of transient voltage surges. Its integrated ESD protection and low capacitance make it an ideal choice for protecting sensitive electronics, such as those found in mobile devices, automotive, and medical applications. Its low failure rate and RoHS compliance make it perfect for use in industrial, aviation, and communication fields.
