NOTE1
No Suffix type numbers are ±20% with guaranteed limits for only V£, IR, and Vp. Units
with "A" suffix are ±10% with guaranteed limits for V£, IR, and Vp 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%.
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 177- A60Hz rms a.c. current equal to 10% of IZT.
Reverse leakage currents are measured at VR as shown on the table.

NOTES
AVZ is the maximum difference between VZ at IZT and V£ at I^L measured with
the device junction in thermal equilibrium at the ambient temperature of +25°C ±3°C.
