NH · Schottky Barrier Diodes (SBD) · SMB
PL56B from NH, 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 terminal, identified by the white band on the package body; the device is rated 60 V VRRM/VDC and 5.0 A average forward current. |
| 2 | A | passive | Anode terminal, the end opposite the white cathode band; forward voltage is 0.55 V max at IF = 5.0 A, TA = 25℃. |
