4. Important Notes:

️· Mounting Surface Selection: The axial coefficient of expansion (+6PPM/°C) should be considered when selecting a mounting surface to ensure proper thermal stability.
️· Zener Impedance Calculation: Zener impedance is derived by superimposing a 60Hz RMS AC current equal to 10% of the test current (IZT).
️· JEDEC Standard: The maximum allowable change is in accordance with JEDEC standard No. 5.
️· Zener Voltage Range: The zener voltage range is 12.8 volts + 5%.
