# SS58

**hongjiacheng** · Schottky Diodes · SMA(DO-214AC)

SS58 from hongjiacheng, in a SMA(DO-214AC). 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 by the cathode line on the DO-214AC (SMA) body; SS58 is rated 80 V VRRM/VDC and 5.0 A average forward current. |
| 2 | A | passive | Anode, the end opposite the cathode line on the DO-214AC (SMA) body; SS58 surge current rating is 120 A (8.3 ms half-sine). |
