No Suffix type numbers are +20% with guaranteed limits for only V Z , l R , and V F .
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%.
Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C + 3°C.
Zener impedance is derived by superimposing on 1 ZT A 60Hz rms a.c. current equal to
10% of1 ZT.
Reverse leakage currents are measured at V R as shown on the table.
∆V Z is the maximum difference between V Z at l ZT and V Z at l ZL measured
Units with “A” suffix are +10% with guaranteed limits for V Z , l R , and V F . Units with
