CAP300DG-TL

POWER INTEGRATIONS · AC-DC Controllers And Regulators · SO-8

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.
