A strong alternative with matching voltage and package, plus a higher current rating (15A).
Finding a substitute for the SP1060L, a 10A, 60V Schottky rectifier in a TO-277 package, involves balancing voltage/current ratings with forward voltage for optimal efficiency. Several potential upgrades and form-fit alternatives are available.
Most alternatives have a higher forward voltage (Vf), which impacts efficiency and thermals. This is the most critical parameter to verify.
All top candidates use the same TO-277 package, but pinout configuration should be confirmed via datasheet comparison.
Multiple manufacturers produce similar Schottky diodes in this package, providing several sourcing options.
There are several likely form-fit-function replacements for the SP1060L in the same TO-277 package. SP1560L is the closest electrical match with an upgraded current rating. Other parts like ST15100L offer upgrades in both voltage and current but may have higher power loss.
SP1560L by Jiangsu Changjing is the strongest candidate, offering a higher 15A current rating while matching the 60V and TO-277 package. Its forward voltage is very competitive.
The primary risk is an increase in forward voltage (Vf), which would reduce power efficiency and increase heat generation. Pinout must also be verified.
