# SS24FL

**onsemi** · Schottky Barrier Diodes (SBD) · SOD-123F

SS24FL from onsemi, in a SOD-123F. 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 band on the package; for SS24FL the peak reverse voltage VRRM and reverse voltage VR are both 40 V. |
| 2 | Anode | passive | Anode terminal of the Schottky barrier rectifier, rated for 2.0 A average rectified current at TA = 75°C and a non-repetitive peak forward surge current of 50 A at t = 8.3 ms. |

## CAD (KiCad official)

- Symbol: `SS24FL`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123F (KiCad packages3D, STEP)
- 3D model files: `ss24fl-etched.step` / `ss24fl-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ss24fl.step` / `ss24fl.glb` are the bare package body.
