BV03CW is a 3.3V bi-directional TVS diode in a SOD-323 package for ESD protection. This page reviews several potential replacements, highlighting key parametric differences for engineers.

AI replacement insight

Package risklow

All strong candidates use the same SOD-323 package.

Electrical riskmedium

Requires verification of clamping voltage and peak pulse current (Ipp) from datasheets.

Sourcing risklow

Multiple viable alternatives from different manufacturers are available.

Can it be replaced directly?

Direct replacement for BV03CW should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

TPGC03C or SPD9103W for a robust replacement with an upgraded power rating.

Main risk

The main risk is selecting a part with the wrong working voltage, which would fail to protect the 3.3V line. Secondary risks involve lower power or ESD ratings.
