# SM516

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

SM516 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, the end marked with the color band; the device is a 1.0 A surface-mount rectifier with 1600 V VRRM for the SM516. |
| 2 | A | passive | Anode, the end opposite the color band; forward current rating is 1.0 A average at TA=75, with VF of 1.1 V at 1.0 A. |
