NOTES:
1. The part numbers have max / min Zener Voltage as listed. Tolerance of 2% is designated by
a B in place of the C.
2. V
Z
is measured with the device in thermal equilibrium at the lead temperature of
30
o
C + 1
o
C, 3/8 from the diode body.
3. The Zener Impedance is measured by dividing the AC voltage drop across the device
by the AC current applied. The specified limits are for I
Z
(ac) = 0.1 I
Z
(dc) with the ac
frequency = 1.0kHz.
