PMEG4030EP

Nexperia · Schottky Barrier Diodes (SBD) · SOD-128

PMEG4030EP from Nexperia, in a SOD-128. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode; the marking bar on the package indicates the cathode terminal.
2 A passive Anode terminal of the Schottky barrier rectifier; the datasheet gives no electrical limits specific to this pin beyond the device ratings (VR ≤ 40 V, IF(AV) ≤ 3 A).
