Zener Voltage versus Zener Current V Z = 82 thru 200 Volts APPLICATION NOTE Since the actual voltage available from a given Zener diode is temperature dependent, it is necessary to determine junction temperature under any set of operating conditions in order to calculate its value. The following procedure is recommended: Lead Temperature, T L, should be determined from: T L = LA P D + T A LA is the lead-to-ambient thermal resistance and P D is the power dissipation. Junction Temperature, T J, may be found from: T J = T L + T JL T JL 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 for dc power. T JL = JL P D For worst-case design, using expected limits of I Z, limits of P D and the extremes of T J ( T J ) may be estimated. Changes in voltage, V Z, can then be found from: V = VZ T J VZ, 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 capability. Surge limitations are given in Figure 5. They are lower than would be expected by considering only junction temperature, as current crowding effects cause temperatures to be extremely high in small spots resulting in device degradation should the limits of Figure 5 be exceeded. 6
