# HFM106

**LRC** · Diodes - General Purpose · DO-214AC(SMA)

HFM106 from LRC, in a DO-214AC(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, marked by the color band on the package; HFM106 has VRRM 600V and 1.0A average forward current. |
| 2 | A | passive | Anode terminal, the end opposite the cathode color band; HFM106 is an ultrafast glass passivated rectifier rated 600V. |

## CAD (KiCad official)

- Symbol: `HFM106`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
- 3D model files: `hfm106-etched.step` / `hfm106-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hfm106.step` / `hfm106.glb` are the bare package body.
