ZD

ESD-Zener diode: 6.1 V typ., max 5 mA;

RST(ON) < 250 Ω at 1.6 mA, ESD zener diodes are not

to be used as voltage clamp at DC conditions.

Operation in this mode may result in a drift of the zener

voltage (increase of up to 1 V).

ZDI1 6.1 V typ., ESD zener diodes are not to be used

as voltage clamp at DC conditions. Operation in this

mode may result in a drift of the zener voltage

(increase of up to 1 V).
