The CM1214A-01SO is a single-channel PicoGuard ESD Suppressor/TVS Diode manufactured by ON Semiconductor. It is used for protection from electrostatic discharge and for transient voltage suppression. It has a 5.5V Breakdown Voltage, a 12.3mA Reverse Leakage Current, and a 2.25pF Clamping Capacitance. This ESD Suppressor has an operating temperature range of -55°C to +150°C, so it can be used for many commercial and industrial applications. It also has a low profile package, which makes it easier to use in space-constrained applications. The CM1214A-01SO is a great solution for electronic systems that require ESD/TVS protection.
