CAP300DG-TL from POWER INTEGRATIONS, in a SO-8. 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 | NC | unconnected | Not connected per Figure 4; the datasheet says electrical connections are made only to pins 2, 3, 6 and 7, and recommends coupling pins 1-4 together on the PCB. |
| 2 | D1 | passive | Terminal D1 of the two-terminal X capacitor discharge device; the D1-to-D2 voltage must not exceed 1000 V in either polarity (absolute maximum), and pins 1-4 should be coupled on the PCB. |
| 3 | D1 | passive | Terminal D1 of the two-terminal X capacitor discharge device; the D1-to-D2 voltage must not exceed 1000 V in either polarity (absolute maximum), and pins 1-4 should be coupled on the PCB. |
| 4 | NC | unconnected | Not connected per Figure 4; the datasheet says electrical connections are made only to pins 2, 3, 6 and 7, and recommends coupling pins 1-4 together on the PCB. |
| 5 | NC | unconnected | Not connected per Figure 4; the datasheet says electrical connections are made only to pins 2, 3, 6 and 7, and recommends coupling pins 5-8 together on the PCB. |
| 6 | D2 | passive | Terminal D2 of the two-terminal X capacitor discharge device; the D1-to-D2 voltage must not exceed 1000 V in either polarity (absolute maximum), and pins 5-8 should be coupled on the PCB. |
| 7 | D2 | passive | Terminal D2 of the two-terminal X capacitor discharge device; the D1-to-D2 voltage must not exceed 1000 V in either polarity (absolute maximum), and pins 5-8 should be coupled on the PCB. |
| 8 | NC | unconnected | Not connected per Figure 4; the datasheet says electrical connections are made only to pins 2, 3, 6 and 7, and recommends coupling pins 5-8 together on the PCB. |
