Well, Jackson was a protectionist, but of course the largest tariff hike in the last century was Smoot-Hawley. Sen Smoot and Rep Hawley were not Democrats, and neither was President Hoover who enacted their Bill.
Smoot and Hawley were building on the tariff hikes of Fordney-McCumber in 1922. Again, Rep Fordney and Sen McCumber were not Democrats and again, neither was President Harding who signed it.
I am sure that Democrats have supported tariffs in the past too, but don't pretend that they have not been a Republican policy as well.
 Oh, and it seems that more recent Republican Presidents have increased tariffs at some point:Reagan in the 80s
Even though we had the firepower, we lost the battle on trade within the Reagan administration. Remember the infamous “voluntary restraint agreement,” in which the Japanese agreed to restrict car exports to the U.S.? It was all a total horror show, one that Reagan supporters like to sweep under the rug. But as Douglas Irwin suggests, that’s hard to do. Indeed, the share of American imports covered by some sort of trade restriction soared under “free-trader” Reagan, moving from only 8% in 1975 to 21% by 1984.
And of course the last hike of steel tariffs by GW Bush in 2002
The administration has announced a complicated schedule of supposedly temporary high tariffs (ranging up to 30%) on different kinds of steel. Something like $8 billion of imports from Europe, Japan, South Korea and other countries will be affected, about 10% of the world market. It would be bad enough if things stopped there. The policy as it stands will make most Americans worse off, by forcing them to pay more for their steel. Except in the short term it will also do little to help the people it is intended to help—namely, workers in the parts of America's steel industry that cannot compete with foreign suppliers or with America's own more productive mini-mills.
And yes, I know Clinton also increased tariffs in the late 90s, leading to a trade war.
