Symbol Parameter Value Unit
VKA Cathode Voltage 37 V IKA Cathode Current Range (Continuous) −100 ~ +150 mA IREF Reference Input Current Range −0.05 ~ +10 mA RθJA Thermal Resistance Junction−Air (Note 1) (Note 2) 350 °C/W MF Suffix Package IREF Power Dissipation (Note 3) (Note 4) 350 mW MF Suffix Package TJ Junction Temperature 150 _C TOPR Operating Temperature Range −25 ~ +85 _C TSTG Storage Temperature Range −65 ~ +150 _C Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. Thermal resistance test board: Size: 1.6 mm x 76.2 mm x 114.3 mm (1S0P)) JEDEC Standard: JESD51−3, JESD51−7 2. Assume no ambient airflow. 3. TJMAX = 150°C; Ratings apply to ambient temperature at 25°C. 4. Power dissipation calculation: PD = (TJ − TA) / RθJA.
RECOMMENDED OPERATING RANGES Symbol Parameter Min. Max. Unit
VKA Cathode Voltage VREF 36 V IKA Cathode Current 1 100 mA Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended Operating Ranges limits may affect device reliability.
