The JEDEC type numbers shown (B suffix) have a +/- 5 % tolerance on nominal Zener voltage. 2. Zener voltage (V Z ) is measured with junction in thermal equilibrium with 30 °C base temperature. The test currents (I ZT ) have been selected so that at nominal voltages the dissipation is a constant 12.5 watts. This results in a nominal junction temperature rise of 18.75 °C. 3. The Zener impedance is derived from the 60 cycle ac voltage, which results when an 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. A curve showing the variation of Zener impedance vs. Zener current for six representative types is shown in Figure 3. Also see MicroNote 202 for further information. 4. The values of I ZM are calculated for a +/- 5 % tolerance on nominal Zener voltage. Allowance has been made for the rise in Zener voltage above V ZT that results from Zener impedance and the increase in junction temperature as power dissipation approaches 50 watts. In the case of individual diodes, I ZM is that value of current that results in a dissipation of 50 watts.
