The double diodes in SOT23 packages are really confusing since there are several configurations possible, and they are all existing. Pin 1 2 3 ----------- Pin 1 A1, C1A2, C2 Pin 2 SOT23 C1, A1C2, A2 ----------- Pin 3 A1, C1C2, A2 C1, A1A2, C2
That is what I use as pin naming convention for the schematic.
