# GBU1506SF

**YFW** · Bridge Rectifiers · GBU

GBU1506SF from YFW, in a GBU. 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 of the bridge, the leftmost lead marked '-' on the body; the datasheet gives no pin-specific limits, only 15 A average forward current for the bridge. |
| 2 | 2 | passive | AC input terminal, the second lead from the left marked '~'; the bridge is rated for VRRM of 600 V (GBU1506SF). |
| 3 | 3 | passive | AC input terminal, the third lead from the left marked '~'; the bridge is rated for VRMS of 420 V (GBU1506SF). |
| 4 | + | passive | DC positive output of the bridge, the rightmost lead marked '+' on the body; the datasheet gives no pin-specific limits, only 15 A average forward current for the bridge. |
