Comchip · Schottky Barrier Diodes (SBD) · DO-214AB
ACDBC340-HF from Comchip, in a DO-214AB. 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 terminal marked by the cathode band on the DO-214AB (SMC) body; the device blocks up to 40 V (VRRM) for ACDBC340-HF and carries 3 A average forward current. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; forward voltage is max 0.55 V at IF=3A, 25°C for ACDBC340-HF. |
