ELECTRICAL CHARACTERISTICS

Tamb = 2 5°C unless otherwise specified. Notes 1. The quoted values ofΔVref are based on a constant current IZ. Two factors can causeΔVref to change, namely the differential resistance rdif and the temperature coefficient SZ. a) As the max. rdif of the device can be 50Ω , a change of 0.01 mA in the current through the reference diode will result in aΔVref of 0.01 mA× 50 Ω = 0.5 mV. This level ofΔVref is not significant on a BZV10 (ΔVref< 46 mV), it is however very significant on a BZV14 (ΔVref< 2.3 mV). b) The temperature coefficient of the reference voltage SZ is a function of IZ. Reference diodes are classified at the specified test current, and the SZ of the reference diode will be different at different levels of IZ. The absolute value of IZ is important, however, the stability of IZ, once the level has been set, is far more significant. This applies particularly to the BZV13 and BZV14. The effect of the stability of IZ on SZ is shown in Fig.2. 2. All reference diodes are characterized by the ‘box method’. This guarantees a maximum voltage excursion (ΔVref) over the specified temperature range, at the specified test current (IZ), verified by tests at indicated temperature points within the range. VZ is measured and recorded at each temperature specified. TheΔVref between the highest and lowest values must not exceed the maximumΔVref given. Therefore the temperature coefficient is only given as a reference. It may be derived from: THERMAL CHARACTERISTICS SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
