BCS65S04D3

Bestirpower · SiC Diodes · DFN-8(5x6)

BCS65S04D3 from Bestirpower, in a DFN-8(5x6). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A passive Anode. Connected internally to the SiC Schottky die anode. Multiple anode pads (pins 1-3) are electrically common and should be tied together on the PCB for current sharing.
2 A passive Anode. Electrically common with pins 1 and 3; tie all anode pads together on the PCB.
3 A passive Anode. Electrically common with pins 1 and 2; tie all anode pads together on the PCB.
4 NC unconnected No internal connection. Leave floating or tie to anode potential.
5 K passive Cathode. Connected to the SiC Schottky die cathode and to the exposed thermal pad on the package underside. Pins 5-8 are electrically common with the thermal pad and must all be tied together for current handling and heat dissipation.
6 K passive Cathode. Electrically common with pins 5, 7, 8, and the exposed thermal pad.
7 K passive Cathode. Electrically common with pins 5, 6, 8, and the exposed thermal pad.
8 K passive Cathode. Electrically common with pins 5, 6, 7, and the exposed thermal pad on the package underside; used as the primary heat-conduction path to the PCB.
9 K (Thermal Pad) passive Exposed thermal pad on package bottom, internally connected to the cathode. Must be soldered to the cathode copper plane for proper thermal (RθJC = 2.17 °C/W) and electrical performance.
