6 Specifications 6.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VKA Cathode Voltage(2) 37 V IKA Continuos Cathode Current Range –100 150 mA II(ref) Reference Input Current –0.05 10 mA TJ Operating Junction Temperature Range 150 °C Tstg Storage Temperature Range –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to ANODE, unless otherwise noted.
6.2 ESD Ratings VALUE UNIT
Electrostatic Human body model (HBM), per ANSI/ESDA/JEDEC JS-001pins(1) ±2000 V(ESD) V discharge Charged-device model (CDM), per JEDEC specification JESD22-C101 (2) ±1000 (1) JEDEC document JEP155 states that 500V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500V HBM is possible with the necessary precautions. (2) JEDEC document JEP157 states that 250V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250V CDM is possible with the necessary precautions.

6.4 Recommended Operating Conditions
See (1)
MIN MAX UNIT
VKA Cathode Voltage Vref 36 V IKA Continuous Cathode Current Range 1 100 mA TL43xxC 0 70 TA Operating Free-Air Temperature TL43xxI –40 85 °C TL43xxQ –40 125 (1) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
