SBDB40100TCTB 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 Schottky barrier rectifier, which is rated for a 100 V peak repetitive reverse voltage and 40 A average rectified output current (2×20 A). |
| 2 | CATHODE | passive | Cathode terminal of the Schottky barrier rectifier, rated for 100 V VRRM and 40 A average output current (2×20 A) per the maximum ratings. |
| 3 | ANODE | passive | Second anode terminal, labelled ANODE in the TO-263-2L pinout alongside pin 1, for the 100 V, 40 A (2×20 A) Schottky rectifier. |
