# KBL410

**MDD（Microdiode Electronics）** · Bridge Rectifiers · KBL

KBL410 from MDD（Microdiode Electronics）, in a KBL. 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 of the bridge, marked + on the body; the KBL410 is rated 1000 V VRRM and 4.0 A average forward output current at TA=50°C. |
| 2 | AC1 | passive | AC input terminal (~) of the bridge; the KBL410 is rated 700 V maximum RMS voltage. |
| 3 | AC2 | passive | AC input terminal (~) of the bridge; the KBL410 is rated 700 V maximum RMS voltage. |
| 4 | - | power_in | Negative DC output of the bridge, marked - on the body, which serves as the DC return. |

## CAD (KiCad official)

- Symbol: `KBL410`
- Footprint: `Diode_THT:Diode_Bridge_Vishay_KBL`
- 3D model: KBL (KiCad packages3D, STEP)
- 3D model files: `kbl410-etched.step` / `kbl410-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `kbl410.step` / `kbl410.glb` are the bare package body.
