Zener Voltage versus Zener Current Vz = 82 thru 200 Volts APPLICATION NOTE Since the actual voltage available from a given zener diode is temperature dependent, it is necessary to determine junc- . J tion temperature under any set of operating conditions in order to calculate its value. The following procedure is recom- mended: Lead Temperature, T_, should be determined from: TL = 9a Pp + Ta 6: Is the lead-to-ambient thermal resistance and Pp is the power dissipation. Junction Temperature, Ty, may be found from: Ty=TL+ATyy AT). is the increase in junction temperature above the lead temperature and may be found from Figure 4 for a train of power pulses or from Figure 5 for de power. * ATYL= Oy. Pp For worst-case design, using expected limits of Iz, limits of Pp andthe extremes of Ty (ATy) may be estimated. Changes in voltage, Vz, can then be found from: AV = @yz ATy @yz, 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 resistance. For best regulation, keep current excursions as low as possible. Data of Figure 4 should not be used to compute surge capa- bility. Surge limitations are given in Figure 6. They are lower than would be expected by considering only junction tempera- ture, as current crowding effects cause temperatures to be ex- tremely high in small spots resulting in device degradation should the limits of Figure 6 be exceeded.
