Can I get a pair of schottky diodes in a single chip?
They're simply called "double Schottky diodes" :-). They often come in different configurations, like for instance the BAT54:  


  BAT54A: common anode
  BAT54C: common cathode
  BAT54S: in series, one diode's cathode connects to the other's anode
  BAT54: is the single diode version
