What component is this?

Hi,

Not sure if its the correct forum, however, does anyone recognize these components? "CCB" 745. This at the output of an DAC, so i am guessing this is may be some protection diodes(maybe 15v zeners?) but they where arranged a bit different than expected. SOT-23 package

It should be a 2SC3326-B SOT-23 transistor​
