The Germans looked capable of scoring every time they broke as they raced to a 3-0 halftime lead against the ineffective four-times former champions.
Marco Reus put the Germans ahead after eight minutes, combining with Mario Goetze in a deadly counter-attack down the right before slipping the ball between goalkeeper Kenneth Vermeer's legs.
With Dortmund needing only a point to go through, Goetze added the second in the 36th minute and Lewandowski scored from a rebound five minutes later. Although Ajax had plenty of possession, Lewandowski added his second in the 67th minute before Daniel Hoesen scored a late consolation.
