A good Zener diode works well, but when you look closely at the datasheet, you’ll see that you need to source more than a few milliamps in order to realize an accurate Zener voltage (V z).

Now's the time to give up on a pure zener diode and go to a temperature-compensated zener. The 1N935 has a zener voltage of 9.075V; a tolerance of 5%; a temperature coefficient of 2 mV/°C; and a zener ...
