  • These differ from regular diodes by what happens when you exceed it’s voltage rating. A normal diode burns up, and is usually damaged by heat. However, a zener instead allows current to flow backward through it. This can be used to essentially drain off excess voltage to ground, so that it stabilizes at 5.1V (which is this diode’s rating).

No public wish lists :(
