*JE D EC R egist er ed Data. †Not JEDEC Data.
NOTES: 1. Zener Voltage (VZ) is measured w ith junction in thermal equilibrium with still air at a temperature of 25oC. The test currents (IZT ) at
nom inal voltages provide a constant 0.25 watts.
2. 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 impedan ce is measu red at 2 points to ensure a sharp knee on the breakdown curve
and to el iminate unstable units. See Micr oNote 202 for variation in dynamic impedan ce with different Zener currents.
3. These values of IZM may often be exceeded in the case of in dividual diodes. The values shown are calculated for a unit at the high
v oltage 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 r ange.
