# ER202

**LGE** · Super Barrier Rectifiers (SBR) · DO-15

ER202 from LGE, in a DO-15. 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, the axial lead marked by the color band; the ER202 blocks 200 V DC (VRRM 200 V) and conducts up to 2.0 A average forward current. |
| 2 | A | passive | Anode, the axial lead opposite the color band; forward voltage is 1.7 V max at 2.0 A. |
