NOTE 2 The zener impedance is derived from the 60 HZ ac voltage, which results when an ac current having an r.m.s. value equal to 10% of the DC zener current (Ir or Ix) is superimposed on Izr or Ix. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve, thereby elimi- nating unstable units. NOTE 3 Temperature coefficient (yz). Test conditions for temperature coefficient are as follows: a. Tor = 7.6 mA, Tr = 25C, T, = 125C (1N5221A, B thru 1N5242A, B.) b. Ipr = Rated Inr, Ti = 25C, T, = 125C (1N5243A, B thru 1N5281A, B.)
