BZT52C15S is a 15 V SOD-323 Zener diode. The closest listed candidate is MM3Z15BW, but pinout and leakage need review.

AI replacement insight

Electrical riskmedium

Zener voltage, leakage, and ZZT affect clamp accuracy.

Package riskmedium

SOD-323 matches, but pinout is not checked.

Firmware risklow

No firmware interface involved.

Sourcing riskmedium

Some lifecycle fields are blank.

Can it be replaced directly?

No verified pin-compatible replacement is confirmed from the provided evidence.

Best replacement path

Review MM3Z15BW first; use MM3Z16BW only with relaxed clamp voltage limits.

Main risk

Unverified pinout and missing leakage or impedance details.
