ZENER LEAKAGE CURRENT REGULATION LOW TYPE VOLTAGE TEST IMPEDANCE FACTOR V Z NUMBER V Z @ lZT CURRENT Z ZT @ lZT l R VR ∆VZ CURRENT VOLTS l ZT OHMS µ Adc VOLTS l ZL (Note 1) mAdc (Note 2) VOLTS (Note 3) mAdc NOTE 1 Suffix “B” voltage range equals nominal Zener voltage +5%. Suffix “A” equals + 10%. No Suffix equals +20%. Zener voltage is read using a pulse measurement, 10 milliseconds maximum. "C" suffix = +2% and "D" suffix = +1%. NOTE 2 Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current equal to 10% of lZT. NOTE 3 ∆VZ is the maximum difference between VZ @ 1 ZT and VZ at 1ZL measured with the device junction in thermal equilibrium at an ambient temperature of +25° + 3°C. BACKSIDE IS CATHODE
