Is there a pin-compatible replacement for DSS16?

Yes, parts like DSK36 and DSK110 are available in the same SOD-123FL package and are considered form-fit replacements. However, you must review their electrical parameters, such as voltage rating and forward voltage, to ensure they are suitable for your application.

What risks should I check before replacing DSS16?

Key risks include: 1) Diode Type: Ensure the replacement is a Schottky diode, not a standard or fast recovery type. 2) Voltage Rating: The replacement should have a voltage rating of at least 60V, preferably with an engineering margin. 3) Forward Voltage (Vf): A higher Vf will increase power loss and heat.

DSS16 Alternatives, Datasheet & Cross Reference | FUXINSEMI

DSS16 is a 60V, 1A Schottky rectifier in a SOD-123FL package, used for high-efficiency rectification. When seeking alternatives, prioritize Schottky diodes with similar or better voltage and current ratings while matching the package.

AI replacement insight

Electrical riskmedium

Must verify diode type, voltage rating, and forward voltage to ensure circuit compatibility.

Package risklow

Several candidates share the same SOD-123FL package, ensuring a direct fit on the PCB.

Sourcing risklow

Multiple manufacturers produce suitable Schottky diodes in this package and rating class.

Can it be replaced directly?

No perfect drop-in replacement was found. DSK110 is a strong functional alternative with a higher voltage rating but slightly worse forward voltage. DSK36 is also strong but lacks a voltage safety margin.

Best replacement path

DSK110 for voltage safety, or DSK36 for higher current and lower Vf if voltage margin is not critical.

Main risk

The primary risk is selecting a non-Schottky diode, which will have significantly higher forward voltage and different switching behavior, likely causing circuit failure.

Recommended alternatives

A form-fit Schottky diode with a higher voltage rating but also a higher forward voltage drop.
