Zener impedance is derived by superimposing on lzt a 60Hz A.C current equal to 10% of IZT Note 2. The maximum allowable change observed over the entire temperature range i.e, the diode voltage will not exceed the specified mV at any discrete temperature between the established limits. Note 3. Voltage measurments to be performed 15 seconds after application of DC current. 1.000 (25.4) Min .300 (7.62) Max .018 (.457) Dia Max Color Band Denotes Cathode .107 (2.71) Dia Max
