Note 1. Nominal voltage for all types is 19.2 volts ±5%
Note 2. Referred to as the “box” measurement method, the VZT 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 ZZT is derived from the resulting ac voltage developed when a 60Hz, rms, ac current equal to 10% of the dc zener
current IZT is superimposed on IZT.
Note 5. To specify radiation hardened devices, use “RH” prefix instead of “1N”.
