*************************************************************** * Infineon Technologies AG * GUMMEL-POON MODEL IN SPICE 2G6 SYNTAX * VALID UP TO 10 GHZ * >>> BFP420 <<< * (C) 2012 Infineon Technologies AG * Version 2.1 January 2012 *************************************************************** * - Please use the global SPICE GP parameter TEMP to specify the * junction temperature of the device in your application to get * correct simulation results. This procedure is necessary because * the GP model does not consider the self heating of the device. * - TEMP is calculated by TEMP=TA+Pdc*(RthJS+RthSA). The junction * temperature TEMP is the sum of the ambient temperature TA and * the increment of temperature caused by the dissipated DC power Pdc. * - RthJS is the thermal resistance between the junction and the * soldering point. RthJS for this device is 260 K/W. RthSA is the * thermal resistance of the PCB, from the soldering point to the * ambient. For determination of RthSA please refer to Infineon's * Application Note "Thermal Resistance Calculation" AN077. * - The model has been verified in the junction temperature range * -25°C to +125°C. * - TNOM=25 °C is the nominal ambient temperature during measurement * for the parameter extraction. Please do not change this value. **************************************************************** *.OPTION TNOM=25, GMIN= 1.00e-12 *BFP420 C B E1 E2 .SUBCKT BFP420 1 2 3 4 * CBEPAR 22 33 5.592E-014 CBCPAR 22 11 1.143E-013 CCEPAR 11 33 1.596E-013 LB 22 20 7.42E-010 LE 33 30 1.656E-010 LC 11 10 7.7E-010 CBEPCK 20 30 4.741E-014 CBCPCK 20 10 1.135E-015 CCEPCK 10 30 4.48E-014 LBX 20 2 2.339E-010 LEX 30 35 4.189E-011 LCX 10 1 2.243E-010 * RE1 35 3 1E-03 RE2 35 4 1E-03 RSub 55 33 176.4 * Diode_sub 55 11 M_Diode_sub * Q1 11 22 33 55 M_BFP420 * .MODEL M_Diode_sub D( + IS = 4.356E-015 + N = 1.02 + RS = 0.1 + CJO = 4E-014 + TNOM = 25) * .MODEL M_BFP420 NPN( + TNOM = 25 + IS = 3.753E-017 + BF = 140.8 + NF = 0.9996 + VAF = 59.18 + IKF = 0.6604 + ISE = 1E-014 + NE = 2 + BR = 13.61 + NR = 0.9938 + VAR = 2.685 + IKR = 0.007013 + ISC = 3.49E-016 + NC = 1.5 + RB = 11.99 + IRB = 0 + RBM = 1.521 + RE = 0.3062 + RC = 2.152 + XTB = 0.1187 + EG = 1.11 + XTI = 4.162 + CJE = 5.621E-013 + VJE = 0.4892 + MJE = 0.2565 + TF = 4.83855E-012 + XTF = 6.245 + VTF = 10.66 + ITF = 0.5436 + PTF = 0 + CJC = 1.227E-013 + VJC = 0.8453 + MJC = 0.6803 + XCJC = 0.7 + TR = 4.7E-009 + CJS = 4.757E-013 + MJS = 1 + VJS = 0.5323 + FC = 0.4148 + KF = 65.9E-12 + AF = 2.0) *************************************************************** * .ENDS BFP420
