Overview
The SL05T1G is a low capacitance ESD protection diode manufactured by onsemi. This device is designed to provide transient overvoltage protection for high-speed interfaces such as communication systems, computers, and computer peripherals. It features a unique integrated solution that includes a surge protection diode in series with a compensating diode, significantly reducing the overall capacitance to less than 5 pF. This makes it ideal for applications requiring minimal signal distortion and high-speed data transmission.
