Electrical specifications @ T
A
= +25°C (unless otherwise specified).
NOTE 1: No Suffix type numbers are ±20% with guaranteed limits for only V
Z
, l
R
, and V
F
. Units with “A” suffix are ±10% with guaranteed limits for V
Z
, l
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%.
NOTE 2: Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C.
NOTE 3: Zener impedance is derived by superimposing on I
ZT
A 60 Hz rms a.c. current equal to 10% of I
ZT
