The CM12310-A2S0 is a member of the XtremeESD™ product family and is specifically designed for next generation deep submicron ASIC protection. 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-A2S0 incorporates the PicoGuard XP™ dual stage ESD architecture which offers dramatically higher system level ESD protection compared with traditional single clamp designs. In addition, the CM1231-A2S0 provides a controlled filter roll-off for even greater spurious EMI suppression and signal integrity. The CM1231-A2S0 protects against ESD pulses up to ±12kV contact on the "OUT" pins per the IEC 61000-4-2 standard.

CM1231-A2SO also features easily routed "pass-through" differential pinouts in a 6-lead SOT23 package.
