PMEG4010EH,115 is a 40V, 1A Schottky rectifier in a compact SOD123F package from Nexperia. When seeking alternatives, prioritize parts with a matching package, low forward voltage (VF), and equivalent or better voltage/current ratings.

AI replacement insight

Package riskhigh

Many alternatives are in different packages (SMA, SMB) and require a PCB redesign.

Electrical riskmedium

Ensure any replacement is a Schottky diode with a similarly low forward voltage (VF) to maintain efficiency.

Can it be replaced directly?

Direct replacement for PMEG4010EH,115 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The best path is to use PMEG4010CEH,115, a variant from the same Nexperia family with a matching package and improved forward voltage.

Main risk

The main risk is selecting a part with a different package (e.g., SMA, SMB) which requires a new PCB layout, or a non-Schottky diode with higher forward voltage, impacting circuit efficiency.
