CM1231-02SO Description

Short technical summary and product information.

The CM1231-02SO is a two-channel low-capacitance ESD protection array from onsemi, belonging to the XtremeESD product family. It incorporates PicoGuard XP dual-stage ESD architecture for enhanced system-level ESD protection compared to traditional single-clamp designs. The device provides steering (rail-to-rail) ESD protection for two unidirectional channels, with a typical clamping voltage of 9V. It can withstand ESD pulses up to ±12kV contact discharge per IEC 61000-4-2 on the OUT pins.

 

Key electrical characteristics include a peak pulse current rating of 1A (8/20µs), power line protection capability, and excellent matching performance: series resistor matching of ±10mΩ typical and differential input capacitance matching of 0.02pF typical. These features make the CM1231-02SO ideal for high-speed data lines requiring low capacitive loading.

 

The device is housed in a surface-mount SOT-23-6 package (also referred to as supplier device package SOT-23-6) and supports an operating temperature range of -40°C to 85°C. It is supplied in tape and reel packaging with a standard quantity of 3000 units. The device is RoHS3 compliant and lead-free (Pb-Free).
