Note 1: No suffix indicates a 20% tolerance on nominal VZ, Suffix A denotes a 10% tolerance, B denotes a 5%
tolerance,
C
denotes
a
2% tolerance.
2: Zener voltage(VZ) measured at TL = 30oC. Voltage measurement to be performed 20 seconds after
application of DC current.
3: The Zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an
rms value equal to 10% of the DC Zener current(IZT or IZK) is superimposed on IZT or IZK.
