SBR5100 from LRC, in a TO-277A. 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 | A | passive | Anode lead (one of two small terminals on the TO-277A package), which carries up to 5.0 A average forward current (IF(AV) at Tc = 75°C) with 100 V maximum DC blocking voltage. |
| 2 | A | passive | Anode lead (second of two small terminals, electrically common with the other anode lead), which carries up to 5.0 A average forward current (IF(AV) at Tc = 75°C) with 100 V maximum DC blocking voltage. |
| 3 | K | passive | Cathode, the large exposed tab/pad of the TO-277A package, which is also the main heat-spreading pad (RθJC 8 °C/W typical) and is rated for 100 V maximum repetitive peak reverse voltage. |
