SD15C is a 15V bidirectional TVS diode in a SOD-323 package. This page reviews potential replacements, focusing on electrical and mechanical compatibility for overvoltage protection circuits.

AI replacement insight

Electrical risklow

For matched or stronger candidates, electrical risk is low. Parametrically weaker options require analysis.

Package risklow

All recommended alternatives use the same SOD-323 package, minimizing layout changes.

Sourcing risklow

Multiple vendors offer compatible parts, improving supply chain resilience.

Can it be replaced directly?

Direct replacement for SD15C should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with Datasheet verified or Strong match candidates for SD15C, then review parametric alternatives for package and electrical fit.

Main risk

The main risk is selecting a part with incorrect voltage ratings or lower power/current handling, which could compromise circuit protection.
