GSOT05-HE3-08

TVS - diodes are a type of electronic component that helps filter out or protect against voltage spikes. The GSOT05-HE3-08 is a transient voltage suppressor protection diode specifically developed for printed circuit boards (PCBs). It is a three-terminal device that employs high surge capability, low leakage current, and low capacitance for board-level protection. This article will discuss the characteristics, applications, and working principles of GSOT05-HE3-08.

The characteristics of the GSOT05-HE3-08 are composed of its small size, low capacitance, high output current, and low voltage. Its small size, only 5x5x3mm, allows it to be placed in small and narrow places on a PCB. Also, as the leakage current is only 5 μA (maximum), its reliability for over-voltage protection is greatly increased. The capacitance of the GSOT05-HE3-08 is very low (less than 1.1pF), and so it is suitable for high-frequency circuits. Additionally, its peak performance current is 5.5A, which is more than enough for most applications. The breakdown voltage or clamping voltage of the GSOT05-HE3-08 is 8V, making it suitable for low voltage applications.

GSOT05-HE3-08 applications mainly include automotive use due to its fast response, low leakage, and small size. Specifically, it can be used in automotive body control systems or power-distribution lines to protect against transients or short-term over-voltage spikes. It can also be used in personal electronics, such as cell phones and laptops, to prevent damage that could be caused by the high-energy voltage spikes from nearby power lines. Overall, it is suitable for any application in which over-voltage protection is needed.

The working principle of GSOT05-HE3-08 is based on the concept of a zener diode and a avalanche diode combined in a single device. A zener diode is a type of diode that is designed to conduct when its breakdown voltage is reached. The zener diode nose current passes through the junction of the zener diode and avalanche diode, which allows the avalanche diode to operate. The avalanche diode has a much more rapid response time than the zener diode, and it discharges the excess current into the circuit. This helps to protect the circuit by dissipating the extra charge buildup, while still allowing the circuit to continue to operate.

In conclusion, the GSOT05-HE3-08 is a transient voltage suppressor protection diode developed for printed circuit boards, which is characterized by its small size, low capacitance, high output current, and low voltage. Its applications mainly include automotive and personal electronics, and its working principle comprises of a zener diode and avalanche diode.
