Maximum Surge Power 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 = 9LAPpD + Ta 8LA is the fead-to-ambient thermal resistance (C/W) and Pp is the power dissipation. The value for 64 will vary and depends on the device mounting method. 6LA is generally 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 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: Ty = Tr + ATUL oi > ez O.1 3S eo 0.05 == 0.03 36 0.02 eH 0.01 = 0,005 Wy = 0.003 wi Gt 0.002 GG 0.001 ci 8; 0.0005 2 0.0003 == 0.0002 0.0001 1 2 5 10 20 50 100 6200 500 1K NOMINAL Vz (VOLTS) Figure 4. Typical Reverse Leakage AT JL is the increase in junction temperature above the lead temperature and may be found from Figure 2 for a train of power pulses (L = 3/8 inch) or fram Figure 10 for de power. ATJL = 9JL PD For worst-case design, using expected limits of 1z, limits of Pp and the extremes of Tj (ATy) may be estimated. Changes in voltage, Vz, can then be found from: AV = 6yz ATy 6vz, 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 resistance. 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 would be expected by considering only junction temper- ature, as current crowding effects cause temperatures to be extremely high in small spots resulting in device degradation should the limits of Figure'3 be exceeded.

A standard tolerance of +5% is indicated by adding an A suffix to the MZP type numbers. A C suffix would indicate a +2% tolerance and a "D" suffix would indicate a +1% tolerance. The tolerance on the 1M type numbers is indicated by the digits fol- lowing ZS inthe part number. 10 indicates 10%, 5 indicates 5%, 2 indicates 2% and 1 indicates 1%. NOTE 2 ZENER VOLTAGE (Vz) MEASUREMENT Motorola guarantees the zener voltage when measured at 80 seconds while maintaining the lead temperature {TL} at 30C = 1C, 3/8 from the diode body. NOTE 3 ZENER IMPEDANCE (22) DERIVATION The zener impedance is derived from the 60 cycle ac voltage, which results when an ac current having an rms value equal to 10% of the dc zener current (Iz or !zK) is superimposed on {27 or IZK. NOTE 4 SURGE CURRENT (i,) 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 cur- rent, Izy, per JEDEC registration, however, actual device capability is as described in Figure 3. *Indicates JEDEC Registered Data for the 1N4728 Series Motorola reserves the right to make changes without further notice to any products herein to improve reliability, function or design.
