4 / 37 page www.ti.com ABSOLUTE MAXIMUM RATINGS DISSIPATION RATING TABLE RECOMMENDED OPERATING CONDITIONS ELECTRICAL CHARACTERISTICS TPA0312 SLOS335A – DECEMBER 2000 – REVISED OCTOBER 2004 over operating free-air temperature range (unless otherwise noted)(1) VDD Supply voltage 6 V VI Input voltage –0.3 V to VDD +0.3 V Continuous total power dissipation Internally limited (see Dissipation Rating Table) TA Operating free-air temperature range –40 °C to 85°C TJ Operating junction temperature range –40 °C to 150°C Tstg Storage temperature range –65 °C to 85°C Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds 260 °C (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. 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. PACKAGE TA≤ 25°C DERATING FACTOR TA = 70°C TA = 85°C PWP 2.7 W(1) 21.8 mW/ °C 1.7 W 1.4 W (1) See the Texas Instruments document, PowerPAD Thermally Enhanced Package Application Report (literature number SLMA002), for more information on the PowerPAD package. The thermal data was measured on a PCB layout based on the information in the section entitled Texas Instruments Recommended Board for PowerPAD of the before-mentioned document.
