mastrila Posted May 2, 2004 Report Share Posted May 2, 2004 I need to replace a power transistor in switching power supply.The only markings on the metal case (TO-3) are "D711". Could it be a2SD711? Can you help me find a datasheet for it?Mastrila. Quote Link to comment Share on other sites More sharing options...
