Happy New Year one and all.
Over the past several years, I've done various conversions from NPN finals to 2030 or IRF520 MOSFETS with mixed results.
In single final radios, I typically see the MOST gain with the IRF520 versus the 2SC1969. In dual final radios, it's a 50/50 split between a beta matched pair of 1969's, vs. twin IRF520's.
However, recently it has come to my attention that Fairchild makes a MOSFET called the FQP13N10 (as used in the Stryker SR-955HPC for example) that is a direct drop in replacement for the IRF520, but can dissipate more power (i.e.: the IRF520 being a 60W vs 13N10 being a 65W device.) However, while the wattage dissipation ratings are pretty much inconsequential, the current handling capability of the 13N10 at 12.8A vs. the 520 at 9.2A caught my attention.
Therefore, my question is:
Is there any "benefit" to using the FQP13N10 MOSFETS as compared to the IRF520's, or is it pretty much a 'moot' point?
Thanks and 73.
