TVS diodes are mainly Surge Protective Devices (SPD), which are used to protect equipment from damaging electric surges. The USB50815CE3/TR13 is a high reliability, thermally protected, low-capacitance bidirectional transient voltage suppressor designed specifically to protect high speed data lines. It is ideal for applications such as USB, Serial ATA (SATA), Digital Video Interconnect (DVI), Camera Link, HDMI, and other digital signal lines.

The USB50815CE3/TR13 is made up of semiconductor components that work together to prevent voltage surges from reaching sensitive electronics and other components. It is a low-capacitance two-port, bidirectional, transient voltage suppressor designed to protect data lines from excessive voltages. The device features a low-capacitance port-to-port design, compact footprint, and low maximum dissipation. The USB50815CE3/TR13 is offered in an industry standard, thermally protected SOT23 package for use in a wide variety of high speed digital data line applications that require fast response and high reliability.

The device is designed to protect sensitive electronic components from damage due to electrostatic discharge (ESD) and other abrupt voltage transients that occur on the data lines. The on-chip thermal protection is designed to eliminate the need for additional protection components, such as TVS diode arrays, on the data lines. It also provides an effective impedance path for high-frequency ESD levels, which helps to reduce radiation and crosstalk. The device has a low-capacitance design, which allows it to be placed close to the end devices and still offer good performance.

The USB50815CE3/TR13 operates by clamping positive and negative voltage transients on the data line to safe levels before they can damage the components connected to the line. When a voltage surge occurs, the USB50815CE3/TR13 utilizes the charge stored in the capacitor to quickly reduce the overvoltage to a safe level. This is done by changing the gate voltage of the transistors in the device, which increases the current flow and reduces the voltage. Once the surge is over, the capacitor is recharged and the transistors revert to their initial state.

The USB50815CE3/TR13 is ideal for high speed digital data line applications where fast response, low power dissipation and high reliability are critical. It is designed to protect against ESD, transients, and other high speed digital data line applications. The device is offered in an industry standard SOT23 package and is suitable for a wide range of high speed digital applications, such as USB, SATA, DVI, Camera Link, HDMI, and other digital signal lines.
