BV03C-H is a 3.3V bi-directional TVS diode in a SOD-323 package, designed for ESD protection. Finding a suitable replacement requires matching the package, working voltage, and key protection parameters like power rating and clamping voltage.

AI replacement insight

Electrical riskmedium

Clamping voltage and power rating must be carefully checked to ensure adequate protection.

Package risklow

SOD-323 is a standard package with many compatible options.

Sourcing risklow

Multiple manufacturers produce similar 3.3V TVS diodes in this package.

Can it be replaced directly?

Direct replacement for BV03C-H should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

WS03DLC-B from Leiditech appears to be the strongest candidate, offering an upgrade in power rating and clamping voltage.

Main risk

The main risk is selecting a part with incorrect working voltage or a significantly weaker power rating or clamping voltage, which would compromise circuit protection.
