SMAJ26CA is a widely-sourced 400W, 26V bidirectional TVS diode in an SMA package for surge protection. Alternatives exist with identical specs or as functional upgrades in different packages.

AI replacement insight

Electrical risklow

Low for cross-vendor parts, medium for parametric alternatives.

Package riskhigh

High if considering parts in different packages like SMB, which require a new PCB layout.

Sourcing risklow

Low, as SMAJ26CA is a multi-sourced component.

Can it be replaced directly?

Yes, the SMAJ26CA is a standard part number offered by multiple manufacturers, which are considered direct replacements.

Best replacement path

Use a cross-vendor SMAJ26CA for a direct, low-risk replacement.

Main risk

The main risk is selecting an alternative with an incorrect package (e.g., SMB) or a lower electrical rating, such as peak pulse current.
