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. NOTE 2 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 um = a of S a) u T.

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 Vzy7 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.
