Notes
1. The quoted values of ∆Vref are based on a constant current IZ. Two factors can cause ∆Vref to change with IZ, namely
the differential resistance rdif and the temperature coefficient SZ.
a) Each change of IZ can result in a maximum change of ∆Vref as follows: ∆Vref (mV) = ∆IZ (mA) × 15 Ω
taking into account that rdif is max. 15 Ω.
b) The temperature coefficient of the reference voltage SZ is also a function of IZ. However, for these reference
diodes SZ varies max. ±0.05 mV/K or ±0.001%/K when IZ is between 6 and 10 mA, so this effect can be neglected
in practice for these types.
2. The temperature coefficient of the reference voltage is obtained from the following formula:
