# SK54BL_R1_00001

**PANJIT International** · Schottky Diodes · SMB(DO-214AA)

SK54BL_R1_00001 from PANJIT International, in a SMB(DO-214AA). 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 terminal, marked by the color band at the cathode end of the package; the device is rated for a maximum repetitive peak reverse voltage of 40 V and a maximum average forward rectified current of 5 A. |
| 2 | Anode | passive | Anode terminal, the end opposite the color band; forward voltage is specified up to 5 A (typical 0.44 V at IF = 5 A at TJ = 25 °C, maximum 0.46 V). |
