TSS Thyristor Surge Suppressors Agent Brand Series

A Transient Solid State Switch (TSS) is a semiconductor device used to protect a circuit from transient overvoltage damage. It protects sensitive components in the circuit mainly by absorbing and dispersing high energy transient overvoltages in the circuit instantaneously. TSS, also known as surge suppression thyristor, is a PNPN junction four-layer device made of semiconductor technology, whose voltammetry characteristics are similar to those of thyristors, with typical switching characteristics.

The principle of TSS is that when the voltage in the circuit exceeds its rated value, the TSS quickly switches on, creating a short circuit that drains the overvoltage to the ground or other safe path. This rapid response makes TSS play an important role in the simulation and design of lightning protection products.

TSS is widely used in communication, security, industrial and other electronic products communication line protection. It is not only suitable for the protection of DC power supplies, but also can be used for the protection of AC power supplies, but can not be used directly on the AC line.

In the selection, the following parameters need to be considered: on-voltage (VDRM), breakdown voltage (VRRM), response time and static capacitance (C). The basic principle of selection is to ensure that the on-voltage is greater than the operating voltage on the circuit to provide adequate protection.
