Part Review and Datasheet Update
Thought for 6 mins 43 sec
I found and attached the official Littelfuse datasheet URL. The first datasheet extraction timed out, so I’m retrying with narrower queries for the pinout and package details.

The symbol has four numbered terminals but no functional pin descriptions, so I’m adding the datasheet pin functions to make the part usable and reviewable.

Completed the CPC1709J part review and updated the project’s Datasheet URL to the official Littelfuse/IXYS datasheet.
What I found/updated:
- MPN: CPC1709J
- Manufacturer: IXYS Integrated Circuits / Littelfuse
- Package: ISOPLUS-264, 4-lead
- Description: 1-Form-A normally-open DC OptoMOS solid-state relay
- Key specs: 60 V blocking, 9 A free-air, 22.8 A with 5°C/W heatsink, 0.05 Ω on-resistance, 2500 Vrms isolation, 10 mA input control current
- Symbol pin descriptions were missing, so I added:
- Pin 1: Load/output +
- Pin 2: Load/output −
- Pin 3: Input LED/control −
- Pin 4: Input LED/control +
Open items / flags:
- The footprint appears consistent with a 4-lead ISOPLUS-264 layout, but the exact mechanical drawing should still be visually checked against the datasheet page drawing before release.
- No functional mismatch remains in the schematic symbol after adding pin descriptions.
Suggested next steps:
- Visually compare the footprint against the datasheet mechanical drawing.
- Add/verify 3D model alignment if this part will be used mechanically.
- Run a final part-quality review before publishing or reusing in designs.
