# CPC1019NTR

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

CPC1019NTR 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; the input control current to activate is 2 mA max (0.15 mA typ at IL=750 mA) and the reverse input voltage must not exceed 5 V. |
| 2 | - Control | passive | LED cathode input of the internal infrared LED; the input control current must not exceed 50 mA continuous and the reverse input voltage is rated 5 V. |
| 3 | Load | passive | MOSFET output switch terminal; blocking voltage is 60 VP, continuous load current is 750 mADC (1 A AC peak), and on-resistance is 0.6 Ω max at IL=750 mA. |
| 4 | Load | passive | MOSFET output switch terminal, paired with pin 3 as the normally-open load contact; blocking voltage is 60 VP and continuous load current is 750 mADC. |
