See further notes on following page.
NOTES:
1. The JEDEC type numbers shown (B suffix) have a +/- 5% tolerance on nominal zener voltage. If other
tolerance is required consult factory. The suffix A is used to identify +/-10% tolerance; no suffix or just R
indicates +/-20% tolerance: C suffix indicates +/-2% tolerance; and D suffix indicates +/-1%.
2. Standard polarity units have the anode connected to the case. Reverse polarity (cathode-to-case) units are
available and are indicated by suffix R in the part number.
3. Zener Voltage (VZ) is measured with junction in thermal equilibrium with 30°C base temperature. The test
currents (IZT) 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.
4. 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 (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. 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.
5. The values of IZM are calculated for a +/-5% tolerance on nominal zener voltage. Allowance has been made
for the rise in zener voltage above VZT that results from zener impedance and the increase in junction
temperature as power dissipation approaches 50 watts. In the case of individual diodes, IZM is that value of
current that results in a dissipation of 50 watts.
