**Yangzhou Yangjie Elec Tech** · Bridge Rectifiers · DBS

DBL205S from Yangzhou Yangjie Elec Tech, 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 | - | passive | DC negative output terminal of the bridge rectifier, marked '-' on the body at the top-left lead in the outline drawing. |
| 2 | + | passive | DC positive output terminal of the bridge rectifier, marked '+' on the body at the top-right lead in the outline drawing. |
| 3 | 3 | passive | AC input terminal marked '~' on the body (bottom-left lead); the bridge is rated at VRRM 600 V for DBL205S and IO 2.0 A. |
| 4 | 4 | passive | AC input terminal marked '~' on the body (bottom-right lead); the bridge is rated at VRRM 600 V for DBL205S and IO 2.0 A. |
