No suffix indicates a ±5% tolerance on nominal V
Z
, C denotes a ±2% tolerance, and D denotes a ±1% tolerance.
Zener voltage (V
z
) is measured at T
L
= 30 °C. Voltage measurement to be performed 90 seconds after application of dc current.
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
or I
).
4. V
f
at 200 mA 1.2 volts maximum and V
f
at 1.0 A 1.5 volts maximum.
