# 1N5821RLG

**onsemi** · Schottky Diodes · DO-201AD

1N5821RLG from onsemi, in a DO-201AD. 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 | CATHODE | passive | Cathode is marked by the polarity band, and the datasheet's lead temperature reference point is the cathode lead 1/32 inch from the case. |
| 2 | ANODE | passive | Anode is the opposite lead from the polarity band; the datasheet gives no electrical limit specific to this pin. |
