1. The JEDEC type numbers shown above have a standard tolerance of +/- 5% of the nominal Zener volume. C suffix signifies 2% toler-
ance, D suffix signifies 1% tolerance. V
Z
is measured with the diode in thermal equilibrium at 25°C + 3°C.
2. The Zener impedance is derived from the 60Hz ac voltage, which results when an ac current having an rms value equal to 10% of the
DC Zener current (I
ZT
or I
ZK
) is superimposed on I
ZT
or I
ZK
. Zener impedance is measured at two points to insure a sharp knee on the
breakdown curve and eliminate unstable units.
3. The reverse surge current is measured at 25
o
C ambient using a 1/2 square wave or equivalent sine wave pulse 1/120 second duration
superimposed on I
ZT
.
