ESD-Zener diode: 6.1 V typ., max 5.0 mA; RST(ON) < 375 Ω

at 1.6 mA, ESD zener diodes are not to be used as voltage

clamp at DC conditions. Operation in this mode may resul

t in

a drift of the zener voltage (increase of up to 1 V).

In case of reverse battery the load current has to be

limited by the load. Temperature protection is not

active
