TVS - Diodes

A Transient Voltage Suppressor (TVS) diode is a type of diode that is designed to protect a circuit from overvoltages that are caused by transients or other electrical disturbances. The name transient itself speaks to the fact that these spikes or other irregularities last for a short period in the power supply. These devices have been used for many different applications for a long time, such as protecting automotive electronics from surges caused by transient voltage fluctuations of the power supply.

The GL05T-E3-08 is a popular TVS diode, specifically designed for automotive applications. It is a unidirectional, bidirectional, and AC-reversal TVS device. As a unidirectional device, it is designed to protect the connected circuits from high voltage transients caused by voltage surges. It is a bidirectional device, however, when connected in reverse, providing bidirectional protection for the connected circuits from both overvoltages and undervolts. Lastly, it also acts as an AC-reversal device, meaning it will automatically switch from a unidirectional protection device to a bidirectional TVS in the event of an AC power reversal.

In terms of its working principle, the GL05T-E3-08 utilizes a zener breakdown to limit the maximum voltage that can pass through it. When the voltage across the diode reaches the diode’s rated breakdown voltage, current starts to flow through the device and creates a voltage drop across the device, limiting the amount of voltage that can pass through. This voltage drop will absorb the energy of the transient voltage surge before it can reach the connected circuits, protecting them from damage.

The GL05T-E3-08 also provides a wide range of operating temperature capacity, from -55°C to 150°C. In addition, it can provide instantaneous protection for transients at various peak pulse currents up to 8.0A. These features make the GL05T-E3-08 a perfect choice for automotive applications that require power surges protection.

In conclusion, the GL05T-E3-08 TVS diode is a robust, reliable, and efficient device designed for a variety of automotive applications. It utilizes zener breakdown to limit the maximum voltage that can pass through it and provides bidirectional and AC-reversal protection from both overvoltages and undervolts. It also outpaces other TVS diodes for peak pulse current and operating temperature, making it a prime choice for automotive applications.
