hello everybody first post on the site. my company does some board repair and we came across an object that i cannot identify. this is a larger surface mount package measuring at 0.236" x 0.26" with a designation of CR. all black on top with etching IR3f9742L. to me this indicates a diode by international rectifier (infineon technologies now) possibly package 723fl but i cant find anything guaranteeing that on the web. i have ST5s smart tweezers and on the diode setting it shows a forward voltage of 0.23V. can anyone assist me in figuring out this diodes true number? anything would be appreciated. if i am inside of the wrong location please let me know. after reading the post in the sticky i am confident it is just a general electronics question.
