TOLERANCE AND VOLTAGE DESIGNATION – The JEDEC type numbers shown are +/-20% with guaranteed limits for only V Z , I R , and V F . Units with A suffix are +/-10% with guaranteed limits for V Z , I R , and V F . Units with guaranteed limits for all six parameters are indicated by a B suffix for +/-5.0% units, C suffix for +/-2.0% and D suffix for +/-1.0%. 2. ZENER VOLTAGE (V Z ) MEASUREMENT – Nominal zener voltage is measured with the device junction in thermal equilibrium with ambient temperature of 25 oC. 3. ZENER IMPEDANCE (Z Z ) MEASUREMENT – The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10% of the dc zener current (I ZT ) is superimposed on I ZT . 4. REVERSE LEAKAGE CURRENT (I R ) – Reverse leakage currents are guaranteed and are measured at V R as shown on the table. 5. MAXIMUM REGULATOR CURRENT (I ZM ) – The maximum current shown is as shown in MIL-PRF-19500/437. 6. MAXIMUM REGULATION FACTOR (∆V Z ) – ∆V Z is the maximum difference between V Z at I ZT and V Z at I ZL measured with the device junction in thermal equilibrium.
