NOTE 2 ZENER IMPEDANCE (22) DERIVATION The zener impedance. is derived from the 60 cycle ac voltage, which results when an ac current having an rifis.vatue equal to 10% of the de zener current (Izy or!74<) is superimposed on !zt or I7K- NOTE 3 REVERSE LEAKAGE CURRENT Ip : Reverse leakage currents are guaranteed only for 5% and 10% zener diodes and are measured at Vg as shown in the Electrical Characteristics Table. NOTE 4 MAXIMUM ZENER CURRENT RATINGS (izq) | 1N3821 thru. 1N3830 Maximum zener current ratings are based on maximum voltage of. 10% tolerance units. 1N3016 thes 1N3051 Maximum zener current ratings are based on maximum voltage of 6% tolerance units, NOTE & SUAGE CURRENT (i,) Surge current is specified as the maximum allowable peak, non- recurrent square-wave current with a specified pulse width, PW. The data. presented in Figures 8 and 9: may be used to find the maximum surge current for a square wave of any pulse width between 0.01 ms and 1000 ms. 4-34 qi Deffeas7ess oo7ao1e 1 . FUL3 _ APPLICATION NOTE. Since the actual voltege available from a given zener diode. is temperature dapendent, it.is necessary to dtermilne junction tem- perature under any set of operating conditions in arder to calculate its value; The following procedure is recommended: Lead Temperature, TL, should be determined from: TL=OLA PotTa OL p, is the lead-to-ambient thermal resistance (C/W) and Pp is the power dissipation. The value for 94 will vary and depends cn the device mounting method. @ a is gen- erally 30-40C/W for the various clips and tie points in common use and for printed circuit board wiring. The temperature of the lead can slso be measured using 8 thefmo- couple placed: on the fead as close as possible.to the tia point. The thermal mass connected to the tie point is normally large enough so that It will not significantly respond-to heat surges generated in the diode as a result of pulsed operation once steady-state condi- tions are achieved. Using the masured value of T_, the junction temperature may be determined by: Ty= TL + ATyL AT yz. is the increase in junction temperature above the {ead temperature and may be found from Figure 6 for a train of - power pultes (L = 3/8 inch) of from Figure 7 for de power. 47 su = Gyn Pp For worst-case design, using expected limits of Iz, limits of Pp and the extremes of TylaTy) may be estimated. Changes In voitage, Vz,.can then be found from: na AV=6yzZATy - Oyz. the zener voltage temperature coefficient, is found from Figures 2 and 3. Under high power-pulse operation, the zener voltage. will. vary with time and may also be affected significantly by the zener resist- ance. For best regulation, keep current excursions as low as possible; Data of Figure 6 should not be used to compute surge capability. Surge limitations are given in Figure 8. They are fower than would be by idering only j ie as current crowding effects cause temperatures to be extremely high in small spots resulting in device degradation should the limits of Figure 8 be exceeded. st my:MOTOROLA SC {DIODES/OPTO} 4h de ff usezesk go?o19 3 i 1N3821 thru 1N3830, 1N3016 thru 1N3051_- 7 Ty TEMPERATURE COEFFICIENTS AND VOLTAGE REGULATION (90% OF THE UNITS ARE IN THE RANGES INDICATED) - -FIGURE 2 TEMPERATURE COEFFICIENT-RANGE FIGURE 3 TEMPERATURE.
