SBDB4060TCTB from Changjing, in a TO-263-2L. 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 | ANODE | passive | Anode terminal of the SBDB4060TCTB Schottky barrier rectifier; the datasheet gives no separate electrical limit for this pin, so the absolute maximum ratings apply (60 V VRRM, 40 A average IO, 150 °C Tj). |
| 2 | CATHODE | passive | Cathode terminal of the SBDB4060TCTB Schottky barrier rectifier; the datasheet gives no separate electrical limit for this pin, so the absolute maximum ratings apply (60 V VRRM, 40 A average IO, 150 °C Tj). |
| 3 | ANODE | passive | Second anode terminal of the SBDB4060TCTB Schottky barrier rectifier; the datasheet gives no separate electrical limit for this pin, so the absolute maximum ratings apply (60 V VRRM, 40 A average IO, 150 °C Tj). |
