GBU1508A
Yangzhou Yangjie Elec Tech · Bridge Rectifiers · GBU
GBU1508A from Yangzhou Yangjie Elec Tech, 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 | - | power_out | Negative DC output of the bridge rectifier, marked '-' on the body; average rectified output current is 15.0 A with heatsink (Tc=100°C) and 3.2 A without (Ta=25°C). |
| 2 | AC1 | passive | AC input terminal, marked 'AC' on the body; the repetitive peak reverse voltage of the GBU1508A is 800 V. |
| 3 | AC2 | passive | Second AC input terminal, marked 'AC' on the body; surge (non-repetitive) forward current is 220 A at 60 Hz half sine wave, 1 cycle, Tj=25°C. |
| 4 | + | power_out | Positive DC output of the bridge rectifier, marked '+' on the body; maximum forward voltage drop per diode is 1.00 V at IFM=7.5 A. |
