Note 1: Nominal voltage for all types 12.8 Volts ±5%.

Note 2: Referred to as “box” measurement method, the ΔVZ is the mezimum 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 since temperature compensated diodes inherently have a non-linear voltage

temperature-characteristic.

Note 4: The dynamic zener impedance ZZT is derived from the resulting AC voltage developed when a 60cps, rms AC current equal to 10% of the DC zener current IZT is

superimposed on IZT.

Note 5: Voltage measurements to be performed 15 seconds after application of DC current.
