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) All voltage values are with respect to ANODE, unless otherwise noted. 7.2 ESD Ratings VALUE UNIT Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V(ESD) Electrostatic discharge V Charged-device model (CDM), per JEDEC specification JESD22- ±1000 C101(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions. 7.3 Thermal Information TL43xx THERMAL METRIC(1) P PW D PS DCK DBV DBZ LP PK UNIT 8 PINS 6 PINS 5 PINS 3 PINS RθJA Junction-to-ambient thermal 85 149 97 95 259 206 206 140 52 resistance °C/W RθJC(top) Junction-to-case (top) thermal 57 65 39 46 87 131 76 55 9 resistance (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report (SPRA953). 7.4 Recommended Operating Conditions See (1) MIN MAX UNIT VKA Cathode voltage Vref 36 V IKA Cathode current 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. 4 Submit Documentation Feedback Copyright © 2004–2015, Texas Instruments Incorporated Product Folder Links: TL431 TL431A TL431B TL432 TL432A TL432B |
