AI replacement insight
Electrical riskhigh
Zener voltage is a critical functional parameter that must match.
Package risklow
SOT-23 is a standard package, but pinout must still be verified.
Sourcing risklow
3.3V SOT-23 Zener diodes are common and available from multiple vendors.
Can it be replaced directly?
No direct, verified pin-to-pin replacement has been identified in this review. Alternatives require careful datasheet comparison of all key electrical parameters.
Best replacement path
Search for Zener diodes with Vz=3.3V, Pd>=250mW, in a SOT-23 package, and verify the pinout via datasheet.
Main risk
The primary risk is selecting a part with a different Zener voltage, which will cause circuit malfunction.
