Oc71 transistor equivalent


Dec 17, 2008 · These are basically AF11x transistors - OC171 is the old designation. Try AF12x transistors as has been suggested. There's not a lot of point in using AF11x types as they're likely to develop internal shorts eventually, just like the OC171. The OC71 will be hopeless and I'm surprised it works at all..
