I have some 10f200s in SOT-23 and they are so tiny I cannot identify pin 1 by normal methods. There does not appear to be a dot or notch in the package and even with my big magnifier I cannot read the writing. So, what I have done is use my meter on diode test mode and with the red lead on (assumed Vss) pin 2 I get a forward voltage on all the port pins of around 0.5V. With the black lead on pin 5 (Vdd) I get a reading on all port pins except MCLR. I have therefore concluded that I have indeed identified pin 1.
However, this is obviously not the way it's done and I suspect that the way they are arranged in the packaging would identify pin 1. So, what is the normal way to identify pin 1 on an SOT-23 device?
