over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VKA Cathode voltage(2) 7 V IK Continuous cathode current –20 20 mA Iref Reference current –0.05 3 mA Operating virtual junction temperature 150 °C Tstg Storage temperature –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) Voltage values are with respect to the anode terminal, unless otherwise noted.
6.2 ESD Ratings PARAMETER DEFINITION VALUE UNIT
Electrostatic Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V(ESD) V discharge Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±1000 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
6.3 Recommended Operating Conditions
over operating free-air temperature range (unless otherwise noted)
MIN MAX UNIT
