Absolute Maximum Ratings
(Voltages specified are relative to the ANODE pin unless otherwise stated.)
Parameter Rating Unit
Cathode Voltage (V
KA
) 20 V
Continuous Cathode Current (I
KA
) 150 mA
Reference Input Current Range (I
REF
) -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.
