Functional alternative with higher ratings in a different package; not a drop-in replacement.
1PS76SB70,115 is a 70V, 70mA Schottky diode in a compact SOD323 package. While no direct pin-compatible replacements are found, several functional alternatives with higher ratings in larger packages are available, which require board redesign.
All alternatives require a board redesign due to larger footprints (SMA/SMB vs SOD323).
Alternatives have superior voltage and current ratings, but check for capacitance differences.
No, there are no direct, pin-compatible replacements for the 1PS76SB70,115 found in this review. All candidates with similar electrical function have different physical packages.
Select a functional alternative like UMW SS510B, which offers higher electrical ratings, but requires a board redesign to accommodate the larger SMB package.
The primary risk is mechanical incompatibility. All reviewed alternatives are in much larger packages (e.g., SMA/SMB) than the target's SOD323, making them physically incompatible without a new PCB layout.

| Feature / factor | 1PS76SB70,115 | SS3150 | SS510 SMA | SS510SMC | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOD323 (SC-76) | DO-214AC, SMA | DO-214AC (SMA) | DO-214AB (SMC) | DO-214AC, SMA / DO-214AC (SMA) / DO-214AB (SMC) — Not form-fit compatible, requires board redesign.; SS510 SMA: Not form-fit compatible, requires board redesign.; SS510SMC: Not form-fit compatible, requires board redesign.; SS520: Not form-fit compatible, requires board redesign. |
| Voltage | 70V | 150V | 100V | 100V | 150V / 100V / 200V — Higher voltage rating.; SS510 SMA: Higher voltage rating.; SS510SMC: Higher voltage rating.; SS520: Significantly higher voltage rating. |
| Current | 0.07A | 3A | 5A | 5A | 3A / 5A — Significantly higher current handling.; SS510 SMA: Significantly higher current handling.; SS510SMC: Significantly higher current handling.; SS520: Significantly higher current handling. |
No direct drop-in alternative was found. Functionally, parts like UMW SS510B are stronger but come in a much larger package (SMB), requiring a board redesign.
