# SS3150-TD

**TDSEMIC** · Schottky Diodes · SMA

SS3150-TD from TDSEMIC, 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, marked by the color band on the SMA/DO-214AC body; the datasheet gives polarity as 'Color band denotes cathode end'. |
| 2 | A | passive | Anode terminal, the end opposite the color band; the device is a 3.0 A surface-mount Schottky barrier rectifier with 80.0 A peak surge (8.3 ms) and 0.95 V max forward voltage at 3.0 A for the 150 V grade. |

## CAD (KiCad official)

- Symbol: `SS3150-TD`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `ss3150-td-etched.step` / `ss3150-td-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ss3150-td.step` / `ss3150-td.glb` are the bare package body.
