Needs validationlow risk
A 10A, 100V Schottky diode in the same TO-277 package with a comparable low forward voltage, making it a strong candidate.
Best Alternatives to ST10100
ST10100 is a 10A, 100V Trench MOS Schottky rectifier in a TO-277 package, known for its low forward voltage. Finding a replacement requires matching the package and key ratings, with special attention to forward voltage (Vf) to maintain circuit efficiency.
AI replacement insight
Electrical riskmedium
Vf mismatch is common and impacts thermals and efficiency.
Package risklow
TO-277 is standard, but pinout must be confirmed.
Can it be replaced directly?
Yes, several parts like ST10100L exist in the same TO-277 package with identical 10A/100V ratings. However, pinout and forward voltage must be verified from datasheets before substitution.
Best replacement path
ST10100L from Jiangsu Changjing is a strong candidate, matching all key parameters including a very low forward voltage.
Main risk
The primary risk is increased power dissipation and reduced efficiency if a substitute has a higher forward voltage (Vf).
