Mason Plumlee added 22 points and 13 rebounds for the Blue Devils (12-0), who needed a huge run late to overcome both a big game from Kevin Foster and a real scare from the Broncos (11-3).
Foster scored 18 of his 29 points in the first half, and his soaring baseline dunk put the Broncos up 45-41 with 16:30 left. But the Broncos managed just one field goal over the next 8 1/2 minutes.
Curry hit two 3-pointers and followed with three layups during the Blue Devils' 26-5 run.
Ryan Kelly had 10 points and 11 rebounds, and Quinn Cook finished with 15 points for Duke, which is 12-0 for the 10th time under coach Mike Krzyzewski. The Blue Devils won their 101st straight nonconference game at Cameron Indoor Stadium.
Evan Roquemore added 17 points while Marc Trasolini and Raymond Cowels III had 10 apiece for Santa Clara, which was playing the No. 1 team for just the second time since 1981 and fell to 0-12 all-time against top-ranked opponents.
