# 1N5819HW

**TECH PUBLIC** · Schottky Diodes · SOD-123

1N5819HW from TECH PUBLIC, in a SOD-123. 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 color band; the datasheet gives 40 V maximum repetitive peak reverse voltage (VRRM) and 1.0 A maximum average forward current for the 1N5819HW. |
| 2 | A | passive | Anode, the end opposite the color band; forward voltage is 0.600 V maximum at IF = 1.0 A and 0.900 V maximum at IF = 3.0 A for the 1N5819HW. |

## CAD (KiCad official)

- Symbol: `1N5819HW`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `1n5819hw-etched.step` / `1n5819hw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `1n5819hw.step` / `1n5819hw.glb` are the bare package body.
