# RS1M-TD

**TDSEMIC** · Fast Recovery / High Efficiency Diodes · SMA

RS1M-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, identified by the cathode band on the body; the 1000 V maximum repetitive peak reverse voltage (VRRM) is blocked when this pin is positive relative to the anode. |
| 2 | A | passive | Anode terminal, the end opposite the cathode band; carries up to 1.0 A average forward current (IF(AV)) with 1.3 V maximum forward voltage at 1.0 A. |

## CAD (KiCad official)

- Symbol: `RS1M-TD`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `rs1m-td-etched.step` / `rs1m-td-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rs1m-td.step` / `rs1m-td.glb` are the bare package body.
