2 / 23 page LM431 SNVS020G – MAY 2000 – REVISED APRIL 2013 www.ti.com DC Test Circuits Note: VZ = VREF (1 + R1/R2) + IREF• R1 Figure 4. Test Circuit for VZ = VREF Figure 5. Test Circuit for VZ > VREF Figure 6. Test Circuit for Off-State Current These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) Storage Temperature Range −65°C to +150°C Operating Temperature Range Industrial (LM431xI) −40°C to +85°C Commercial (LM431xC) 0°C to +70°C Soldering Information Infrared or Convection (20 sec.) 235°C Wave Soldering (10 sec.) 260°C (lead temp.) Cathode Voltage 37V Continuous Cathode Current −10 mA to +150 mA Reference Voltage −0.5V Reference Input Current 10 mA Internal Power Dissipation(3)(4) TO-92 Package 0.78W SOIC Package 0.81W SOT-23 Package 0.28W (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device beyond its rated operating conditions. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications. (3) TJ Max = 150°C. (4) Ratings apply to ambient temperature at 25°C. Above this temperature, derate the TO-92 at 6.2 mW/°C, the SOIC at 6.5 mW/°C, the SOT-23 at 2.2 mW/°C. Operating Conditions Min Max Cathode Voltage VREF 37V Cathode Current 1.0 mA 100 mA 2 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LM431 |
