ZTL431/ZTL432 Absolute Maximum Ratings
(Voltages specified are relative to the Anode pin unless otherwise stated.)
Parameter Rating Unit
Cathode Voltage (VKA) 20 V Continuous Cathode Current (IKA) 150 mA Reference Input Current Range (IREF) -50µA to +10mA — Operating Junction Temperature -40 to +150 °C Storage Temperature -55 to +150 °C Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended periods, may reduce device reliability.
