PMEG040V030EPE-QZ

Nexperia · Schottky Diodes · TO-277

PMEG040V030EPE-QZ from Nexperia, in a TO-277. 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 A passive Anode of the Schottky barrier rectifier; one of two anode leads listed in Table 2 for the CFP15B package.
2 A passive Anode of the Schottky barrier rectifier; one of two anode leads listed in Table 2 for the CFP15B package.
3 K passive Cathode of the Schottky barrier rectifier; the datasheet identifies the cathode tab as the soldering point for the junction-to-solder-point thermal resistance (Rth(j-sp) 3 K/W max).
