BZX79C2V4. . . 75 Series
NOTES:
1. The Zener Voltage is measured under pulse conditions so that T
J
is no more than 2
o
C greater
than T
A
.
2. Part numbers have max / min Zener Voltage as listed. Tolerance of 2% is designated by
a B in place of the C, and 1% by an A.
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.
