CI15S120C3

Tokmas · Schottky Barrier Diodes (SBD) · TO-220-2

CI15S120C3 from Tokmas, in a TO-220-2. 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 PIN 1 passive Terminal marked PIN 1 on the TO-220-2 outline; the datasheet does not state whether it is the anode or the cathode, nor any pin-specific limit.
2 PIN 2 passive Terminal marked PIN 2 on the TO-220-2 outline; the datasheet does not state whether it is the anode or the cathode, nor any pin-specific limit.
