UT-7702 is a PCI to two-port RS-232 serial port card, with a fast transient suppression protector designed to protect the RS-232 interface, can convert single-ended PCI signals into RS-232 signals. Adopt today's advanced TVS tube, under normal circumstances, the TVS tube is in a high group state.
When the two ends of the TVS tube are subjected to an instantaneous high-energy impact, it can reduce the impedance at both ends at a very high speed and absorb a large current, thereby clamping the voltage at both ends to a predetermined value to protect the following circuit components from being damaged by transient high voltage shocks. This protector can effectively suppress lightning (LIGHTNING) and ESD, provide TX/RX 600W lightning surge protection, and the surge and transient overvoltage generated on the line for various reasons, and the extremely small inter-electrode capacitance ensures the high-speed transmission of RS-232.
