NOTES:
1. The JEDEC type numbers shown with suffix A have a standard tolerance of +/-5% on the nominal zener voltage. V
measured
with device in thermal equilibrium in 25
C still air and mounted in test clips, ” from unit body. if tighter tolerance on V
Z
is required,
consult factory.
2.
The zener impedance is derived when a 60 cycle ac current having an rms value equal to 10% of the dc zener current (I
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. See MicroNote 202 for variation in dynamic impedance with different zener currents.
3.
Allowance has been made for the increase in
V
Z
due to Z
Z
and for the increase in junction temperature as the unit approaches
thermal equilibrium at the power dissipation of 1 watt.
