**MDD Microdiode Semiconductor** · Bridge Rectifiers · DBS

DB107S from MDD Microdiode Semiconductor, in a DBS. 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 | + | power_out | Positive DC output terminal of the bridge; the datasheet gives the DB107S maximum repetitive peak reverse voltage as 1000 V and average forward rectified current as 1.0 A at TC=40°C. |
| 2 | - | power_out | Negative DC output terminal of the bridge; the datasheet gives the DB107S maximum repetitive peak reverse voltage as 1000 V and average forward rectified current as 1.0 A at TC=40°C. |
| 3 | 3 | input | AC input terminal of the bridge; the DB107S maximum RMS input voltage is 700 V and the maximum repetitive peak reverse voltage is 1000 V. |
| 4 | 4 | input | AC input terminal of the bridge; the DB107S maximum RMS input voltage is 700 V and the maximum repetitive peak reverse voltage is 1000 V. |

## CAD (KiCad official)

- Symbol: `DB107S`
- Footprint: `Diode_SMD:Diode_Bridge_Vishay_DFS`
- 3D model: DBS (KiCad packages3D, STEP)
- 3D model files: `db107s-etched.step` / `db107s-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `db107s.step` / `db107s.glb` are the bare package body.
