# CD1206-B2100

**BOURNS** · Schottky Diodes · 1206

CD1206-B2100 from BOURNS, in a 1206. 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; the device blocks up to 100 V DC (VRRM 100 V) and passes 2 A average forward current. |
| 2 | A | passive | Anode terminal at the end opposite the cathode band; forward voltage is 0.85 V max at 2 A for the B2100. |
