(42S) P-N Junction Diode Polarization (solver program)
This is a solver program to calculate the polarization voltage of a p-n junction diode by means of a resistor. You can get the polarization current from Shockley's equation that you can find in MOHPC forum too.
VCC: supply voltage (Volts). IS: saturation current (Amps). Typ. 1E-9 for Silicon. VD: diode voltage (Volts). Typ. 0.7 is a good start point. N: quality factor (n=1 ideal diode, 1<n<2 real diodes). T: temperature (Kelvin). R: resistor (Ohms) 00 { 86-Byte Prgm } 01 LBL "DIOD" 02 MVAR "VCC" 03 MVAR "IS" 04 MVAR "VD" 05 MVAR "N" 06 MVAR "T" 07 MVAR "R" 08 RCL "VCC" 09 1.60218ᴇ-19 10 RCL× "VD" 11 1.38064852ᴇ-23 12 ÷ 13 RCL÷ "N" 14 RCL÷ "T" 15 E↑X-1 16 RCL× "IS" 17 RCL× "R" 18 - 19 RCL- "VD" 20 .END. PS: step 15 now includes the proper E↑X-1 thanks to Valentín. Saludos Saluti Cordialement Cumprimentos MfG BR + + + + + Luigi Vampa + Free42 '<3' I + + |
