3. Metallization Details: ️· Top (Anode): Aluminum (Al) - 25,000 Å minimum thickness
️· Back (Cathode): Gold (Au) - 4,000 Å minimum thickness
4. Chip Thickness: ️· 10 Mils (approximately 0.254 mm)
5. Design Notes/Circuit Layout Data: ️· For Zener operation, the cathode must be operated positive with respect to the anode.
6. Dimensional Tolerances: ️· All dimensions + 2 mils.
7. Figures and Graphs (Summarized): ️· Figure 5 (Power Derating Curve): Shows the maximum power dissipation (in Watts) versus ambient temperature (in °C). The maximum power decreases as temperature increases.
️· Figure 5 (Zener Impedance vs. Operating Current): Shows how the Zener impedance changes with the DC operating current. The impedance is generally higher at lower currents.
Important Notes: ️· Tolerance: The table does not provide a consistent tolerance value for the Zener voltage. Note 5 mentions a standard tolerance of "+ 5% of the nominal Zener voltage." You're advised to consult the full datasheet for more precise tolerance information.
️· Full Datasheet: This information is extracted from what you've provided. Always refer to the complete datasheet for the most accurate and comprehensive specifications.
️· Å (Angstrom): 1 Å = 10<sup>-10</sup> meters.
