AI replacement insight

Electrical riskmedium

MM3Z3V3 matches Vz; BZT52C3V6 shifts Vz.

Package riskhigh

No kept part is SOD-523.

Firmware risklow

Passive diode, no firmware.

Sourcing risklow

Kept parts are catalog matched.

Can it be replaced directly?

Direct replacement for BZX584C3V3 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Review MM3Z3V3 first for same 3.3 V function, then verify footprint and polarity.

Main risk

All kept candidates use a different package from SOD-523.
