CM1293A-04SO Description

Short technical summary and product information.

The CM1293A-04SO is a 4-channel low capacitance ESD protection array from ON Semiconductor (now onsemi). It is designed to protect high-speed data lines from electrostatic discharge (ESD) events, meeting IEC 61000-4-2 Level 4 standards with ±8 kV contact discharge capability.

 

Each channel uses a steering (rail-to-rail) topology with pairs of diodes directing ESD current to the supply rails. An integrated Zener diode protects the VCC rail without needing external bypass capacitors. The device offers ultra-low loading capacitance of 2.0 pF maximum (1.5 pF typical I/O to I/O), making it ideal for high-speed interfaces like USB 2.0, IEEE 1394, Serial ATA, DVI, and HDMI.

 

The CM1293A-04SO is housed in a compact SC-74 (SOT-457) surface-mount package with a standard tape and reel packaging quantity of 3000 pieces. It operates over a temperature range of -40°C to 85°C and is RoHS3 compliant and Pb-Free.
