KUU · Schottky Barrier Diodes (SBD) · SMB
KB340B-13-F from KUU, in a SMB. 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 end marked by the color band on the JEDEC SMB body; device blocks up to 40 V DC and passes 3.0 A average forward current. |
| 2 | A | passive | Anode, the end opposite the color band; forward voltage is 0.55 V maximum at 3.0 A. |
