The following procedure is recommended: Lead Temperature, T L , should be determined from: T L = q LA P D + T A O q L A is the lead-to-ambient thermal resistance ( C/W) and Pd is the power dissipation. The value for q L A will vary and depends on the device mounting method. q L A is generally 30-40 OC/W for the various clips and tie points in common use and for printed circuit board wiring. The temperature of the lead can also be measured using a thermocouple placed on the lead as close as possible to the tie poi n 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 conditions are achieved. Using the measured value of TL, the junction temperature may be determined by: T J = T L + D T JL D T JL is the increase in junction temperature above the lead temperature and may be found from Figure 2 for a train of power puls or from Figure 10 for dc power. D T JL = q J L P D For worst-case design, using expected limits of I Z , limits of P D and the extremes of T J ( D T J ) may be estimated. Changes in volta V Z , can then be found from: DV = qV Z DT J q V Z , the zener voltage temperature coefficient, is found from Figures 5 and 6. Under high power-pulse operation, the zener voltage will vary with time and may also be affected significantly by the zener resi s For best regulation, keep current excursions as low as possible. Data of Figure 2 should not be used to compute surge capa-bility. Surge limitations are given in Figure 3. They are lower than w be expected by considering only junction temperature, as current crowding effects cause temperatures to be extremely high in s spots resulting in device degradation should the limits of Figure 3 be exceeded.
