I'm a beginner at electronics and I wanted to buy a 5.1V zener diode with a Pd of 500mW. I've noticed that the test current (Izt) of these diodes are either 50uA, 5mA, or 20mA. I have two questions:
1) What exactly is zener test current?
2) What's the significance of this and how would it affect an electronic circuit?
