TVS (Transient Voltage Suppressor) diodes are designed to protect sensitive, high-value electronic components from potentially damaging voltage spikes caused by electrostatic discharge (ESD), electrical fast transients (EFT) and other related transient events. They are capable of handling short duration voltage spikes of up to several hundreds of volts, and are designed to protect components such as microprocessors, memory chips, and other high value/low power devices.

The SMDB12TR is a type of TVS diode which is designed for transient voltage protection. It is a 12V, dual bi-directional diode, which is capable of dissipating up to 26A of transient current. This makes it an ideal choice for applications that require surge protection up to 12V and peak current ratings up to 26A. The diode can also absorb a wide range of ESD discharges of up to 8kV, and is suitable for use in datasheets, audio equipment, power supplies, and other sensitive equipment.

The working principle of the SMDB12TR is quite simple. When a surge is detected by the diode, the current passes through the diode and is quickly absorbed. This helps to prevent damage to the surrounding components, which can be caused by the overvoltage spikes. The diode works by clamping the voltage down to a safe level, which helps to ensure that the surrounding components are not damaged by the sudden increase in voltage.

The SMDB12TR is an ideal choice for applications that require transient voltage protection. It is an inexpensive and reliable way to protect sensitive electronic components and equipment from damage caused by ESD, EFT, and other transient events. The diode also offers excellent absorption up to 8kV, and can handle peak current ratings up to 26A, making it a versatile solution for a wide range of protection needs.
