Needs validationlow risk
A pin-compatible Fast Recovery Diode with matching voltage, current, and 500ns recovery time in a SOD-123FL package.
Best Alternatives to F7
The GOODWORK F7 is a 1A, 1000V fast recovery rectifier in a compact SOD-123FL package. Its 500ns recovery time makes it ideal for high-frequency power supplies and inverters.
AI replacement insight
Electrical riskhigh
Risk is high if a standard diode is used. Low if a verified fast recovery diode is used.
Package risklow
SOD-123FL is a standard package, ensuring mechanical compatibility.
Can it be replaced directly?
Direct replacement for F7 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use an industry-standard FR107 fast recovery diode from a reputable manufacturer in the same SOD-123FL package.
Main risk
Substituting with a standard (non-fast) recovery diode, which can cause overheating and circuit failure in high-frequency applications.
