Re: A13TA Transistors-odd readings on DMM
These are TO-220 plastic power Transistors. All I know about the Vf is that 614mV was indicated on my Chinese Tester(One of those frequently advertised on eBay for about £10, which tests Caps., Resistors, Diodes & Transistors). With my DMM the voltage readings I get fall away rpidly within a minute or so of applying power to the OSU, so I can't answer the question, except tha 0.6v as is well known is thenormal Vbe for a silicon transistor.
