NOTE:
1.Standard zener voltage tolerance is +/- 5% with a 'C' suffix from BZX84C2V4~BZX84C51 , suffix 'B' is +/- 2% tolerance from BZX84B4V3~BZX84B51.
2.Zener Voltage (Vz) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (TL) AT 30 OC,from the diode body.
3.Zener Impedance (Zz) Derivation. The zener impedance os dervied 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.
4.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, per JEDEC registration; however, actual device capability is as described in Figure 5.
