TVS - Diodes are a special class of semiconductor devices, used to provide protection against high voltages. The SMDA05C-4TR is a TVS - Diode, designed to protect devices from damage due to overvoltage transients.

The SMDA05C-4TR is mainly used in electronic equipment such as TVs, computer monitors, CD players and other consumer electronics. This diode operates in stand-off voltages from 26 to 60V, and provides an excellent protection against overvoltage transients. It has low clamping voltage, low leakage current, and wide stand-off voltage range. It also has low reverse leakage current, good insulation resistance, and no flicker noise.

The SMDA05C-4TR is a four-terminal diode, with an external capacitor and one high-current transistor in the internal circuit. The capacitor forms an RC network with the diode, so that the pulse current generated by the pulse is restricted and the maximum available current is limited. The transistor then forms an active diode, where a voltage greater than the clamping voltage is formed, thereby limiting the voltage that can be applied to the device.

Generally speaking, the working principle of the SMDA05C-4TR is to limit the voltage by a combination of the diode and its external capacitor. When an overvoltage transient occurs, the current through the diode increases quickly, causing the voltage across the diode to be clamped to the reverse breakdown voltage of the diode. This clamped voltage is limited to a safe level, thus protecting the device from damage.

The SMDA05C-4TR is an important part of many devices, helping to protect them from overvoltage transients. With its low clamping voltage, low leakage current, and wide range of operating voltages, this diode is an excellent choice for many applications. With its excellent performance, it is a great choice for providing protection to devices from overvoltage transients.
