# US1M-13-F

**Diodes Incorporated** · Fast Recovery / High Efficiency Diodes · SMA

US1M-13-F from Diodes Incorporated, in a SMA. 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 terminal, the end marked with the cathode band or cathode notch; US1M blocks up to 1000 V VRRM and passes 1.0A average rectified current. |
| 2 | A | passive | Anode terminal, the end opposite the cathode band; US1M carries 1.0A average forward current with a 30A non-repetitive peak surge (8.3ms). |
