Additional Details

The LCDA12C-8.TB typically features a standoff voltage of around 12V. It is designed to handle repetitive ESD strikes without degradation in performance. The device's clamping voltage is typically specified at a given surge current level. The capacitance is an important parameter for high-speed data lines, and the LCDA12C-8.TB is designed to have a low capacitance to minimize signal attenuation and distortion. The operating temperature range is usually specified from -40°C to +85°C. Proper PCB layout is crucial for effective ESD protection. The TVS diode array should be placed as close as possible to the connector or source of the transient voltage.
