MDD
Functional alternative with higher voltage (80V) and current (3A), but requires board redesign.
PMEG6010ELRX is a 60V, 1A Schottky diode in a compact SOD123W package. Finding a direct drop-in replacement requires matching the package and key electrical ratings.
Different footprint (SMB/SMA vs. SOD123W) requires PCB redesign.
Candidates meet or exceed voltage and current ratings.
No direct, pin-compatible replacement for PMEG6010ELRX was found. All candidates require a PCB layout change due to different packages.
For new designs or board revisions, consider SS56B for its higher current capability. For existing boards, sourcing the original PMEG6010ELRX is recommended.
The main risk is the physical package mismatch, making all candidates incompatible without a board redesign.

| Voltage | 60.0V | 80.0V | 150.0V | 200.0V | 80.0V / 150.0V / 200.0V / 60.0V — Higher voltage rating provides more margin.; SS5150B: Higher voltage rating provides more margin.; SS5200B: Higher voltage rating provides more margin.; SS56: Voltage rating matches the target. |
| Current | 1.0A | 3.0A | 5.0A | 5.0A | 3.0A / 5.0A — Higher current rating provides more margin.; SS5150B: Higher current rating provides more margin.; SS5200B: Higher current rating provides more margin.; SS56: Higher current rating provides more margin. |
The best alternative depends on your ability to change the PCB layout. While no direct drop-in replacements are listed, parts like SS56B offer higher current (5A) but come in a larger SMB package.
