Is there a calculator available for determining the series resistance of the diode.(ie RS which is given in the data sheets)
If you are talking about the bulk resistance, you can calculate it if you measure the current through the diode and voltage across it. The voltage across the diode will be the sum of the junction voltage and the voltage across the bulk resistance. If you subtract the junction voltage (from the datasheet for a given current) from the voltage across the diode you will get the voltage across the bulk resistance. Then divide the voltage across the bulk resistance by the current through the diode to get the value if the bulk resistance.Is there a calculator available for determining the series resistance of the diode.(ie RS which is given in the data sheets)
Can you link to a datasheet we can look at? Not all diodes spec Rs.Is there a calculator available for determining the series resistance of the diode.(ie RS which is given in the data sheets)
S stands for series, as the OP said in his first post.The parameter would be Rs - R sub s, or resistance depending on whatever s stands for - if such an animal can be found.
The BA483 spec is for Rd. Rs appears to be another animal.This specification seems to be more relevant for switching diodes. I attached a PDF for a switching diode that specifies the forward resistance.
Also, I've attached a paper that discusses a more complex diode model which includes series resistance and capacitive effects.
