BZT52C33S is a 33V, 200mW Zener diode in a SOD-323 package. Finding a direct replacement requires matching the Zener voltage, power rating, and package.

AI replacement insight

Electrical riskmedium

Zener voltage mismatch requires circuit analysis.

Package risklow

Candidates share the same SOD-323 package.

Sourcing risklow

Alternatives are from the same product family.

Can it be replaced directly?

Direct replacement for BZT52C33S should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Search for Zener diodes with a 33V nominal voltage, >=200mW power rating, in a SOD-323 package. BZT52C30S and BZT52C36S are options if voltage can deviate.

Main risk

The primary risk is a mismatch in Zener voltage, which can affect circuit regulation performance. Pinout also requires verification.
