Voltage measurement to be performed 20 seconds after application of the DC test current. Note 2. The maximum zener current (Izm) shown is for the nominal voltages. The following formula can be used to determine th worst case current for any tolerance device: P Izm = Vzm Where Vzm is the high end of the tolerance specified and P is the rated power of the device. Note 3. Zener impedance is derived from the 1kHz AC voltage which results when an AC current having an RMS value equal to 10% of DC zener current (IZT or IZK) is superimposed on IZT or IZK. 1.000 (25.4) Min .200 (5.08) Max .022 (.509) Dia Max Color Band Denotes Cathode .090 (2.28) Dia Max
