AI replacement insight

Package risklow

Multiple candidates match the SOD-523 package.

Electrical risklow

Key parameters (Vz, Pd) are matched or improved. Secondary parameters need review.

Sourcing riskmedium

Check stock and lead times for all candidates.

Can it be replaced directly?

Yes, parts like LM5Z15VT1G and BZX585-C15,135 are available in the same SOD-523 package with identical Zener voltage and equal or better power ratings.

Best replacement path

BZX585-C15,135 is a strong upgrade path, offering double the power dissipation and AEC-Q101 qualification in the same SOD-523 package.

Main risk

The main risk is ensuring secondary electrical parameters like Zener impedance tolerance and reverse leakage current meet the specific circuit's requirements.
