*JEDEC Registered Data. †Not JEDEC Data. 8000
NOTES: 1. When using JEDEC numbers, B suffix signifies +/-5% tolerance on nominal zener voltage. The suffix A is used to identify +/-10%
tolerance; no suffix indicates +/-20% tolerance: suffix C is used to identify +/- 2%; and suffix D is used to identify +/- 1% tolerance.
2. Zener Voltage (VZ) is measured with junction in thermal equilibrium with still air at a temperature of 25oC. The test currents (IZT) at
nominal voltages provide a constant 0.25 watts.
3. The zener impedance is derived when a 60 cycle ac current having an rms value equal to 10% of the dc zener current (IZT or
IZK) is superimposed on IZT or IZK. Zener impedance is measured at 2 points to ensure a sharp knee on the breakdown curve
and to eliminate unstable units. See MicroNote 202 for variation in dynamic impedance with different zener currents.
4. These values of IZM may often be exceeded in the case of individual diodes. The values shown are calculated for a unit at the high
voltage end of its tolerance range. Allowance has also been made for the rise in zener voltage above VZT that results from zener
impedance and the increase in junction temperature as a unit approaches thermal equilibrium at a dissipation of 1 watt. The IZM
values shown for +/-5% tolerance units may be used with little error for +/-10% tolerance units, but should be reduced by 7% to
include a +/-20% tolerance unit near the high voltage end of its tolerance range.
