Note 1. Nominal voltage for all types is 19.2 volts ±5%
Note 2. Referred to as the “box” measurement method, the
V
ZT
is the maximum voltage variance that will occur as the voltage is scanned through all
temperatures between the temperature range limits.
Note 3. The effective temperature coefficients are tabulated in %/°C primarily for information only because temperature compensated diodes inherently
have a non-linear voltage temperature relationship.
Note 4. The dynamic zener impedance Z
ZT
is derived from the resulting ac voltage developed when a 60Hz, rms, ac current equal to 10% of the dc zener
current I
ZT
is superimposed on I
ZT.
Note 5. To specify radiation hardened devices, use “RH” prefix instead of “1N”.
