Re: Band

This is something that was drilled into our heads when I went through electronics school (a good few moons ago!)... The arrow always points towards negative material on semi-conductors.... example being transistors. look at an NPN transistor. The arrow points outward from the emitter. The reverse is true for a PNP. I suppose positioning depends on whether the diode is reverse biased or not, but that does not reflect which side of the diode is positive/negative.
