CM1231-02SO ESD Protection Diodes by ON Semiconductor

ESD Clamp Protection Array


The CM1231 is specifically designed for sub-micron silicon design. These devices are ideal for protecting systems with high data and clock rates and for circuits requiring low capacitive loading such as USB 2.0. The CM1231-02SO incorporates dual stage ESD architecture which offers dramatically higher system level ESD protection compared with traditional single clamp designs. In addition, the CM1231-02SO provides a controlled filter roll-off for even greater spurious EMI suppression and signal integrity. The CM1231-02SO protects against ESD pulses up to 12 kV contact on the OUT pins per the IEC 61000-4-2 standard. The device also features easily routed pass-through differential pinouts.
