Zener Voltage (V Z) is measured with junction in thermal equilibrium with still air at a temperature of 25oC. The test currents (I ZT ) at nominal 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 (I ZT or I ZK ) is superimposed on I ZT or I ZK . 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. 3. These values of I ZM 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 V ZT that results from Zener impedance and the increase in junction temperature as a unit approaches thermal equilibrium at a dissipation of 1 watt. The I ZM 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.
