ACDBB540-HF from Comchip, 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, marked by the cathode band on the DO-214AA (SMB) body; reverse voltage rated 40 V (VRRM/VDC). |
| 2 | A | passive | Anode terminal of the Schottky rectifier, opposite the cathode band; average forward current 5 A with VF of 0.55 V max at IF = 5 A. |
