Notes:
- 1. Halogen free Green products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
- 2. On FR - 4 Board With Minimum Recommended Solder Pad Layout.
- 3. Mounted on 5.0mm (0.013mm Thick) Land Areas.
- 4. Standard Zener Voltage Tolerance is 5% With a "B" suffix (e.g.: MMSZ5225B), Suffix "C" is 2% Tolerance.
- 5. Zener Voltage (VZ) Measurement. Guarantees the Zener Voltage When Measured at 90 Seconds While Maintaining the Lead Temperature (TL) at 25C, From the Diode Body.
- 6. Zener Impedance (ZZ) 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 (IZT or IZK) is Superimposed on IZT or IZK.
