BAT54HT1G
FUXINSEMI
Needs validationlow risk
A strong cross-vendor alternative from onsemi with nearly identical key electrical parameters in the same SOD-323 package.
Best Alternatives to LBAT54HT1G
The LBAT54HT1G is a 30V, 200mA Schottky diode in a compact SOD-323 package, valued for its fast switching and low forward voltage. Finding a suitable replacement requires matching these key electrical parameters and package.
AI replacement insight
Electrical risklow
Low if sticking to BAT54-series parts. Medium for other Schottky diodes.
Package risklow
SOD-323 is a standard package with consistent dimensions.
Sourcing risklow
The BAT54 family is widely available from multiple vendors.
Can it be replaced directly?
Direct replacement for LBAT54HT1G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The most direct path is using BAT54HT1G from a major manufacturer like onsemi, which is a widely sourced cross-vendor equivalent.
Main risk
The main risk when substituting is an increase in forward voltage (Vf), which can reduce system efficiency and increase heat.
