SS36(SMA)
Niu Hang
Needs validationlow risk
Strong pin-compatible upgrade with higher voltage (60V) and current (3A) ratings and better efficiency.
Best Alternatives to SS24-MS
The SS24-MS is a 40V, 2A Schottky diode in an SMA package, used for high-efficiency rectification. Several pin-compatible alternatives exist, offering higher current or voltage ratings, but require checking the minimum operating temperature.
AI replacement insight
Electrical risklow
Most candidates are upgrades in voltage/current. Check Vf on SS510.
Package risklow
All recommended candidates use the same DO-214AC (SMA) package.
Sourcing risklow
Multiple vendors offer suitable parts in the same family.
Can it be replaced directly?
SS54-MS from the same manufacturer is a strong candidate with higher current capability. The main difference to check is the minimum operating temperature.
Best replacement path
Upgrade to a higher current part like SS36(SMA) or SX34_R1_00001 for better performance, provided the -55°C minimum temperature is acceptable.
Main risk
The primary risk is the reduced low-temperature operating range from -65°C to -55°C, which could affect reliability in cold environments.
