6 / 15 page TGA4943-SL Table IV Power Dissipation and Thermal Properties 1/ Channel operating temperature will directly affect the device median lifetime (Tm). For maximum life, it is recommended that channel temperatures be maintained at the lowest possible levels. 2/ θ jc is modeled based upon hottest stage (stage 3) because there is negligible thermal coupling Parameter Test Conditions Value Notes Thermal Resistance, θjc Vd = 7 V Idq_tot = 300 mA Idq3=190 mA Pd_stage3 = 1.33 W Tbaseplate = 85 °C θ jc = 39.4 °C/W Tchannel = 137.4 °C Tm = 4.3 E+6 Hrs 1/, 2/ Thermal Resistance, θjc Under RF Drive Vout = 8 Vpp, Vd = 7V Id3 = 190 mA Pd_stage3 =1.17 W Tbaseplate = 85 °C θ jc = 39.4 °C/W Tchannel = 131 °C Tm = 9.2 E+6 Hrs Storage Temperature -65 to 150 °C Case Operating Range -65 to 150 ºC 3/ 6 May 2011 © Rev E TriQuint Semiconductor: www. triquint.com (972)994-8465 Fax (972)994-8504 info-networks@tqs.com 2/ θ jc is modeled based upon hottest stage (stage 3) because there is negligible thermal coupling between stages. It is the thermal resistance of the part calculated from the junction to the bottom of the TGA4943-SL package. To calculate the temperature rise, calculate the dissipated power in the third stage (Pdiss = Idq3*Vd3) and multiply by θjc. For example: Tbase = 85 °C, Idq3 = 190 mA, Vd3 = 7V. Pdiss_stage3 = 1.33 W. θ jc=39.4 °C/W. Temperature rise = θjc*Pdiss = 52.4 C; Tchannel = Tbase + Temp rise = 137.4 °C 3/ Case operating range values are for reference only. Channel temperature must not exceed maximum ratings value and must be at value acceptable to customer lifetime requirements. 1.E+04 1.E+05 1.E+06 1.E+07 1.E+08 1.E+09 1.E+10 1.E+11 1.E+12 1.E+13 25 50 75 100 125 150 175 200 Channel Temperature ( C) FET5 ° Median Lifetime (Tm) vs. Channel Temperature |
