Can it be replaced directly?
Direct replacement for SMAJ30A should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Review SMAJ30CA first; verify polarity, pinout, leakage, and temperature.
Main risk
Polarity is not explicit for the target and SMAJ30CA is bidirectional.
