# SM2000

**LGE** · Super Barrier Rectifier (SBR) · DO-213AB

SM2000 from LGE, in a DO-213AB. 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 end, marked by the color band on the DO-213AB molded body; SM2000 blocks up to 2000V VRRM/VDC. |
| 2 | A | passive | Anode end of the rectifier, conducting 1.0A maximum average forward current at TA=75 with 1.1V maximum forward voltage at 1.0A (not stated in this text). |
