B130LAW-7-F is a 30V, 1A Schottky rectifier in a SOD123 package. Several alternatives exist, with 1N5819HWQ-7-F offering a strong pin-compatible upgrade path.

AI replacement insight

Electrical risklow

Low if forward voltage is closely matched. Higher VF increases power loss.

Package risklow

Low for candidates in the same SOD123 package.

Sourcing riskmedium

Check availability and pricing, especially for automotive-grade parts.

Can it be replaced directly?

Yes, 1N5819HWQ-7-F is a strong candidate for direct replacement, offering an improved voltage rating in the same package.

Best replacement path

Upgrade to 1N5819HWQ-7-F for a higher voltage rating and similar performance.

Main risk

The primary risk when substituting Schottky diodes is an increase in forward voltage (VF), which can impact system efficiency and thermal performance.
