PMEG045V100EPE-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 terminal of the Schottky barrier rectifier; Table 2 lists pins 1 and 2 both as anode. |
| 2 | A | passive | Anode terminal of the Schottky barrier rectifier; Table 2 lists pins 1 and 2 both as anode. |
| 3 | K | passive | Cathode terminal of the Schottky barrier rectifier; the cathode tab is the soldering point referenced for the junction-to-solder-point thermal resistance Rth(j-sp) of 3 K/W maximum. |
