Can it be replaced directly?
Direct replacement for SMAJ15CA should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Review SMAJ16CA only if 16V Vrwm, 26V clamp, and 15.4A Ipp are acceptable.
Main risk
Protection threshold and surge margin change.
