Best Alternatives to DS24W-MS

Package: SOD-123FLMSKSEMIDiodes - Rectifiers - SingleDiode Type: SchottkyVoltage - Peak Reverse (VRRM): 40 VCurrent - Average Rectified (IO): 2 AForward Voltage (VF) @ IF: 0.55 V @ 2 AReverse Leakage Current (IR) @ VR: 0.1 mA @ 40 V

DS24W-MS is a 40V, 2A Schottky rectifier in a compact SOD-123FL package, valued for its low forward voltage. Finding a substitute involves balancing stress ratings like voltage and current against efficiency parameters like forward voltage and reverse leakage.

AI replacement insight

Electrical riskhigh

Key parameters like Vf and Ir vary, impacting efficiency and standby power. Some candidates lack voltage margin.

Package risklow

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

Sourcing risklow

Some MPNs like SS34L are generic; ensure you are sourcing from a reputable vendor with a clear datasheet.

Can it be replaced directly?

No perfect drop-in replacement exists in this list; all candidates have parametric trade-offs. PSBD1DF40V2H is parametrically close but has 5x higher reverse leakage, which requires careful review.

Best replacement path

For improved robustness, consider DSS36 or DSS26, which offer higher 60V ratings. However, you must verify that your design can tolerate their higher forward voltage and leakage current.

Main risk

The primary risk is electrical incompatibility. Substituting a part with higher forward voltage (Vf) will increase power loss and heat, while higher reverse leakage (Ir) can drain batteries or affect high-impedance circuits.
