Needs validationlow risk
A classic, multi-vendor pin-compatible replacement with identical ratings and improved reverse leakage.
Best Alternatives to SM4007PL
SM4007PL is a standard 1000V, 1A general-purpose rectifier in a compact SOD-123FL package. Excellent pin-compatible alternatives like 1N4007W and A7 are widely available from multiple manufacturers.
AI replacement insight
Electrical risklow
Key ratings (1000V, 1A, 1.1Vf) are easily matched. Check secondary parameters like Cj and Ir.
Package risklow
The SOD-123FL package is standard, but confirm dimensions from the chosen substitute's datasheet.
Sourcing risklow
Many alternatives are multi-source, commodity parts, reducing sourcing risk.
Can it be replaced directly?
Direct replacement for SM4007PL should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The best replacement path is to use a widely-sourced, industry-standard part like 1N4007W or the common equivalent A7, both in the SOD-123FL package.
Main risk
The main risk when substituting is a mismatch in secondary parameters like junction capacitance, which can impact performance in high-frequency applications.
