Diodes Incorporated and its subsidiaries reserve the right to make modifications, enhancements, improvements, corrections or other changes without further notice to any product herein. Diodes Incorporated does not assume any liability arising out of the application or use of any product Note: The zener diode maintains a nearly constant voltage across RL as long as the zener current is greater than IZK and less than IZM FROM NO LOAD TO FULL LOAD When output terminal of zener diode is open (RL= ), the load current is zero.
Izk is the minimum current. But at this current, the Zener diode voltage will be lower than this 5.6V. And instead of a Zener diode try to use the TL431. I need a zener, and I needed the "knee current" of 1mA, I already tested it on Orcad and it works, but under "1mA" the voltage drops. The Zener impedance is derived from the 60 Hz ac voltage which results when an ac current having an rms value equal to 10% of the Zener current (IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. (1) The Zener impedance is derived from the 1 KHz AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (Izi or IZK) is superimposed on IZT or IZK Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units

Other Zener voltages and tolerances are available upon request. Aug 26, 2015 · The Zener diode should be chosen for Zener voltage, and also for the power rating and package size. Package size is related to heat dissipation. Choose a package with a power rating large enough to keep operating temperatures below datasheet maximum (ideally, much lower).
