TL431/TL432 ADJUSTABLE PRECISION SHUNT REGULATOR Absolute Maximum Ratings (Note 4) Symbol Parameter Rating Unit
VKA Cathode Voltage 40 V IKA Continuous Cathode Current 150 mA IREF Reference Input Current -0.050 to +10 mA TJ Operating Junction Temperature +150 °C TST Storage Temperature -55 to +150 °C SOT23 330 PD Power Dissipation (Notes 5, 6) mW SOT25 500 SO-8* 700 Notes: 4. Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended periods, may reduce device reliability. Unless otherwise stated voltages specified are relative to the ANODE pin. 5. TJ, MAX =150°C. 6. Ratings apply to ambient temperature at 25°C.
