A TVS (transient voltage suppressor) diode is a type of diode designed to protect electrical and electronic equipment from damaging, voltage-induced transients and surges. The SMBJ15CA-13 is a uni-directional, transient voltage suppressor (TVS) diode that provides fast transient over-voltage protection for high-speed data interfaces, such as USB, HDMI, and Display port cables. It features low capacitance (<0.15 pF) and is designed to interface with electromagnetic interference (EMI) filters and low voltage differential signaling (LVDS) systems.

The SMBJ15CA-13 is designed to protect sensitive electronic devices from transient voltage spikes. The diode utilizes an avalanche breakdown capacitor which is triggered when the voltage spike exceeds the breakdown voltage of the diode. The breakdown voltage typically varies between 9 and 16V. When triggered, the capacitor absorbs the transient voltage and dissipates it as heat, ensuring the protected device is not damaged by the surge. The SMBJ15CA-13 also features an integrated Stand-Off Voltage (SOV) of 12 Volts. This SOV prevents the avalanche breakdown capacitor from unintentionally discharging, resulting in better EMI filtering and longer operational life.

The SMBJ15CA-13 is ideal for use in high-speed serial data lines, such as USB, HDMI, and DisplayPort. The diode features low capacitance values which ensure signal integrity is maintained in high speed applications. These low capacitance values help reduce EMI and reduce ESD susceptibility. Additionally, the SMBJ15CA-13 features an integrated Stand-Off Voltage (SOV), allowing it to be used in LVDS and other EMI filtering applications as well.

The SMBJ15CA-13 also features a fast response time, allowing it to protect sensitive electronic systems during transients that rise and fall quickly. This fast response time minimizes the possibility of damaging the protected device, making it ideal for use with sensitive electronic equipment. Additionally, the diode features a low leakage current, ensuring it does not inadvertently damage sensitive electronic equipment.

The SMBJ15CA-13 is an ideal diode for protecting vulnerable electrical and electronic equipment from transient voltage surges and spikes. The diode features a fast response time and low capacitance values, making it ideal for use in high-speed signaling applications. Additionally, the diode features an integrated Stand-Off Voltage (SOV) which allows it to be used with low voltage differential signaling (LVDS) systems and EMI filters. The low leakage current ensures the protected device is not inadvertently damaged.
