A potential pin-compatible upgrade from the same manufacturer with higher voltage and temperature ratings.
PMEG4030EP,115 is a 40V, 3A Schottky rectifier in a SOD-128 package. Key alternatives include pin-compatible upgrades with higher voltage ratings and functional alternates in different packages that require board redesign.
Pin-compatible options have similar or better electricals, but Vf must be checked.
Many functional alternates are in different packages (SMB, SMA) and require a PCB redesign.
Multiple alternatives exist from various manufacturers.
Direct replacement for PMEG4030EP,115 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use PMEG6030EVPX for a direct, upgraded replacement.
The main risk is selecting an alternative with a different package or a higher forward voltage, which can impact board layout and circuit efficiency.

| Feature / factor | PMEG4030EP,115 | PMEG6030EVPX | PMEG6030ELPX | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOD-128 | SOD-128 | SOD-128 | SOD-128 — Same package family (CFP5), likely compatible land pattern.; PMEG6030ELPX: Same package family, likely compatible land pattern. | |
| Voltage | 40V | 60V | 60V | 60V — Higher voltage rating provides more design margin.; PMEG6030ELPX: Higher voltage rating provides more design margin. | |
| Current | 3A | 3A | 3A | 3A — Current rating is identical.; PMEG6030ELPX: Current rating is identical. | |
| Vf | 490mV @ 3A | 475mV @ 3A | 670mV @ 3A | 475mV @ 3A / 670mV @ 3A — Lower forward voltage improves efficiency.; PMEG6030ELPX: Significantly higher forward voltage will increase power loss. | |
| Temperature | 150°C | 175°C | 175°C | 175°C — Higher max operating temperature.; PMEG6030ELPX: Higher max operating temperature. |
Verified drop-in options for PMEG4030EP,115 are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
