Diodes Incorporated
Excellent upgrade with higher voltage and current ratings in the same package and technology.
Find the best replacements for the 1N5819HW1-7-F, a 1A, 40V SBR diode in a SOD123F package. This guide provides verified upgrade paths and functional alternatives from Diodes Inc. and other manufacturers.
Low if VF and technology are matched or improved. Medium if using standard Schottky.
Low, as many alternatives exist in the same SOD123F package. High if a different package is considered.
Multiple viable alternatives are available from the original manufacturer and others.
The SBR2U60S1F-7 is the best direct replacement, offering superior electrical characteristics in the same SOD123F package. PMEG4010CEH,115 is a strong cross-vendor option.
Upgrade to SBR2U60S1F-7 for improved voltage (60V) and current (2A) ratings with no electrical trade-offs.
The main risk is substituting with a standard Schottky diode, which may have different leakage or switching characteristics than the target's SBR technology.
