DSK34
TWGMC
Needs validationmedium risk
DSK34 matches the main 40V 3A SOD-123FL Schottky ratings but needs pinout review.
Best Alternatives to DSS34
DSS34 is a 40V 3A SOD-123FL Schottky rectifier. Several same-package candidates exist, but pin polarity and thermal limits still need review.

Can it be replaced directly?
Direct replacement for DSS34 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with DSK34 or K34; use DSK36/DSS310 only if higher Vf is acceptable.
Main risk
Pin polarity and forward-voltage loss are not fully verified.
