ER2004CT_TO_00001 from PANJIT International, in a ITO-220AB-3. 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 | AC1 | passive | Anode of the first rectifier diode (AC terminal 1); the ER2004CT is rated 400 V VRRM and 10 A per leg (20 A total average). |
| 2 | CATHODE | passive | Common cathode of both diodes (center pin, also the tab connection per the TO-220AB drawing); polarity as marked on the package. |
| 3 | AC3 | passive | Anode of the second rectifier diode (AC terminal 3); the ER2004CT is rated 400 V VRRM and 10 A per leg (20 A total average). |
