Finding a substitute for the onsemi MBR230LSFT1G, a 30V, 2A low forward voltage Schottky diode, requires careful attention to electrical parameters. While several parts share its SOD-123FL package, the key challenge is matching its low forward voltage to maintain system...

AI replacement insight

Electrical riskhigh

The forward voltage of most alternatives is 25-100% higher, impacting efficiency and thermals.

Package risklow

All reviewed candidates use the same SOD-123FL package, ensuring physical compatibility.

Can it be replaced directly?

No direct drop-in replacement with identical low forward voltage is listed. Candidates like DSS34 offer higher voltage and current ratings but have a higher forward voltage, which will increase power loss.

Best replacement path

Upgrade to a 40V/3A part like DSS34 or K34, but you must verify the impact of its higher forward voltage (~0.55V) on system efficiency and thermal performance.

Main risk

Increased power dissipation and reduced efficiency due to candidates having a higher forward voltage (Vf) than the original part.

Questions & answers

The best alternatives are likely DSS34 or K34. They offer higher voltage (40V) and current (3A) ratings in the same package, but you must verify if their higher forward voltage (~0.55V vs 0.43V) is acceptable for your application's efficiency and thermal budget.
