Overview
The CM1214A-01SO is a single-channel ESD (Electrostatic Discharge) protector designed by onsemi to safeguard bipolar signal lines against ESD events. This component is particularly suited for high-speed environments and is available in a 3-lead SOT23-3 package. It is ideal for protecting high-speed interfaces, including RF switches and amplifiers, due to its low sub-1 pF loading capacitance.
