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: V ref1 – V ref2 100 S Z = -------------------------------------- × -------------------- %/K T amb2 – T amb1 V ref nom THERMAL CHARACTERISTICS SYMBOL PARAMETER Rth j-tp thermal resistance from junction to tie-point Rth j-a thermal resistance from junction to ambient CONDITIONS note 1 Note 1.
