Transient voltage suppression diodes, or simply TVS diodes, are specialized devices used to protect electronic components from an overvoltage surge. DE2703900L is a TVS diode manufactured by ISOCOM Company, used to provide efficient protection in high voltage environments. This paper aims to explain the application field and working principle of DE2703900L.

DE2703900L is designed to protect I/O ports of PCs, peripheral devices, and other consumer electronic products from damaging overvoltage, static discharge, and surge transients. It features a 5-way bidirectional glass passivated junction with ultra-fast switching speeds, high reliability, low leakage, and low clamping voltage. It operates at a peak pulse current of 5 kW for 8/20 microseconds and can withstand working voltages up to 8.5 KV. Furthermore, it features excellent ESD immunity and low leakage current.

The main working principle of DE2703900L is based on the avalanche breakdown effect. In short, this occurs when a high reverse bias voltage is applied to a diode with a lightly doped P-N junction. When the voltage applied is increased beyond the breakdown voltage, the diode is said to have entered avalanche breakdown. This causes a rapid increase in current, thus limiting the voltage across the protected device. The DE2703900L is designed to respond quickly to any overvoltage, clamping the voltage and redirecting the flow of current. This helps protect the device from damages caused by the overvoltage.

In summary, DE2703900L is a specialized TVS diode designed for protection of I/O ports of PCs and consumer devices. It features superior performance and reliability, as well as excellent ESD immunity. Its main working principle is based on the avalanche breakdown effect, which helps the diode clamp the voltage in order to protect the device from damage.
