NOTES:

The JEDEC type numbers shown (B suffix) have a +/- 5% tolerance on nominal zener voltage. The suffix A is used to identify +/-10%

tolerance; no suffix indicates +/-20% tolerance. If tighter tolerance is required, consult factory. 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.

Zener Voltage (V_Z) is measured with junction in thermal equilibrium with 30^oC 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^oC .

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_ZTor I_ZK) is superimposed on I_ZTor 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.

The values of I_ZMare calculated for a +/-5% tolerance on nominal zener voltage. Allowance has been made for the rise in zener voltage

above V_ZTthat results from zener impedance and the increase in junction temperature as power dissipation approaches 50 watts. In the

case of individual diodes, I_ZMis that value of current that results in a dissipation of 50 watts.

GRAPHS AND CIRCUITS

Typical circuit connections for anode-to-case and

cathode-to-case polarities (standard and reverse

polarities, respectively).
