NOTE 2: ZENER IMPEDANCE (ZZT) DERIVATION The zener impedance is derived from the 1000 cycle ac volt- age, which results when an ac current having an rms value equal to 10% of the dc zener current (lZT) is superimposed on IZT' .NOTE3:REVERSELEAKAGECURRENTIR Reverse leakage currents are guaranteed and are measured at VR as shown on the table. NOTE 4: MAXIMUM ZENER CURRENT RATINGS (lZM) Maximum zener current ratings are based on maximum zener voltage of the individual units. II 4-93 MLL4099 thru MLL4135, MLL4614 thru MLL4627 ZENER NOISE DENSITY A zener diode generates noise when it is biased in the zener direction. A small part of this noise is due to the internal resistance associated with the device. A larger part of zener noise is a result of the zener breakdown phenomenon and is called microplasma noise. This microplasma noise is generally considered "white" noise with equal amplitude for all frequencies from about zero cycles to approximately 200,000 cycles. To eliminate the higher frequency components of noise a small shunting capacitor can be used. The lower frequency noise generally must be tolerated since a c.
