CPC1135N

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

CPC1135N 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 Positive input of the infrared LED control; input control current to activate is 2 mA max (typ 0.6 mA at IL=120 mA) and the LED forward voltage drop is 0.9 V to 1.5 V at IF=5 mA.
2 , Control input Negative input of the infrared LED control; reverse input voltage is limited to 5 V and reverse input current is 10 µA max at VR=5 V.
3 Load passive One load terminal of the normally-closed OptoMOS output; blocking voltage 350 VP, continuous load current 120 mArms/mADC, peak ±350 mAP for 10 ms, and on-resistance 35 Ω max.
4 Load passive Other load terminal of the normally-closed OptoMOS output; blocking voltage 350 VP, continuous load current 120 mArms/mADC, peak ±350 mAP for 10 ms, and on-resistance 35 Ω max.
