The suffix A is used to identify + 10% tolerance: suffix C is used to identify + 2%; and suffix D is used to identify +1% tolerance; no suffix indicates + 20% tolerance. NOTE2 Zener voltage (Vz) is measured after the test current has been applied for 20 +5 seconds. The device shall be suspended by its leads with the inside edge of the mounting clips between .375 and .500 from the body. Mounting clips shall be maintained at a temperature of 25 +8/-2C. NOTE 3 The zener impedance is derived from the 60 cycle A.C. voltage, which results when an A.C. current 200 175 TAGE TEMPERATURE. 150 COEFFICIENT % / 125 100 75 50 Je / AW INIID14I909 JUNLVeIdW3L TEMPERATURE COEFFICIENT %/C 25 0 1 NOMINAL ZENER VOLTAGE (VOLTS) FIGURE 2 ZENER VOLTAGE TEMPERATURE COEFF. vs. ZENER VOLTAGE 2000 8 a g 8 Typical Capacitance in pF a8 having an R.M.S. value equal to 10% of the D.C. zener current (I77 or Iz,) is superimposed on lz+ or Iyx. Zener impedance is measured at 2 points to insure a sharp knee on the breakdown curve and to eliminate unstable units. NOTE 4 The values of Izy are calculated for a 5% tolerance on nominal zener voltage. Allowance has been made for the rise in zener voltage above Vzy which results from zener impedance and the increase in junction temperature as power dissipation approaches 400 mW. In the case of individual diodes Izy is that value of current which results in a dissipation of 400 mW at 50C lead temperature at 3/8 from body.
