NOTES:
See further notes on following page
1. When using JEDEC numbers an R suffix should be used to signify reversed polarity. The suffixes A and B indicate tolerances
of 10% and 5% respectively. No suffix or just R denotes +/-20% tolerance. Example: 1N3319RB is a REVERSED polarity,
20 volt unit having a +/-5% tolerance on Zener Voltage.
2.
Zener Voltage (
V
Z
) is measured with junction in thermal equilibrium with 30
o
C stud temperature.
zener current for three representative types is shown in Figure 2. Also see Microsemi MicroNote 202.
3.
The Zener impedance is derived from the 60 cycle 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 2 points to ensure a
sharp knee on the breakdown curve and to eliminate unstable units. A curve showing the variation of zener impedance vs.
