SPECIALS AVAILABLE INCLUDE: Nominal zener voltages between the voltages shown and tighter voltage tolerances. For detailed information on price, availability, and delivery, contact your nearest Motorola representative. NOTE 3.

ZENER IMPEDANCE (ZZ) DERIVATION The zener impedance is derived from the 1 kHz cycle ac voltage, which results when an ac current having an rms value equal to 10% of the dc zener current (IZT) or (IZK) is superimposed on IZT or IZK. NOTE 5. SURGE CURRENT (ir) NON-REPETITIVE The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current IZT.

Typical Forward Characteristics 500 mW DO-35 Glass Data Sheet 6-4 Motorola TVS/Zener Device Data GENERAL DATA -- 500 mW DO-35 GLASS 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, TL, should be determined from: TL = LAPD + TA. LA is the lead-to-ambient thermal resistance (C/W) and PD is the power dissipation. The value for LA will vary and depends on the device mounting method. LA is generally 30 to 40C/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 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 conditions are achieved. Using the measured value of TL, the junction temperature may be determined by: TJ = TL + TJL. TJL is the increase in junction temperature above the lead temperature and may be found as follows: TJL = JLPD. JL may be determined from Figure 3 for dc power conditions. For worst-case design, using expected limits of IZ, limits of PD and the extremes of TJ(TJ) may be estimated. Changes in voltage, VZ, can then be found from: V = VZ TJ. VZ, the zener voltage temperature coefficient, is found from Figure 2. 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. 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.
