CPC1125N

Littelfuse IXYS · Solid State Relays (MOS Output) · SOP-4-2.54mm

CPC1125N from Littelfuse IXYS, in a SOP-4-2.54mm. 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 + Control input LED anode input; input control current to activate is 2 mA max, deactivate minimum is 0.1 mA, and reverse input voltage is limited to 5 V.
2 , Control input LED cathode input return; the input LED is rated for 50 mA max control current (10 ms peak 1 A) and 5 V reverse voltage.
3 Load passive One load terminal of the normally closed (1-Form-B) OptoMOS output, rated for 400 V peak blocking voltage and 100 mArms/mADC continuous load current, derated to 60 mA at 85 °C.
4 Load passive Other load terminal of the OptoMOS output, with the same 400 V peak blocking voltage and 100 mArms/mADC continuous limit, plus ±350 mA peak for 10 ms.
