The CM1213A-01SO from onsemi is a unidirectional TVS diode array designed for ESD protection in electronic systems. It uses a steering (rail-to-rail) topology to shunt ESD currents to the power rails, protecting sensitive circuits from electrostatic discharge events. The device provides ESD protection up to ±12kV contact discharge per IEC 61000-4-2 Level 4, making it suitable for a wide range of applications.
Key electrical specifications include a reverse standoff voltage of 3.3V, a clamping voltage of 10V typical at 1A (8/20µs), and a peak pulse current rating of 1A. The device features low channel input capacitance of 0.85pF typical with 0.02pF matching, minimizing signal distortion in high-speed data lines. It operates over a temperature range of -40°C to 85°C.
The CM1213A-01SO is available in a surface-mount SOT-23-3 (TO-236) package, suitable for automated assembly. It is RoHS3 compliant, Pb-free, and halogen-free, meeting environmental standards. The CM1213A family includes SZ-prefixed variants for automotive applications requiring AEC-Q101 qualification. This device is ideal for general purpose ESD protection in consumer, industrial, and automotive electronics.
