Part Information Review and Correction
Thought for 2 mins 18 sec
I reviewed the part metadata, schematic terminals, footprint presence, and the official Infineon datasheet.
- The project already has a Datasheet URL property set to the official Infineon PDF.
- Because a datasheet URL is already present, no Datasheet property update was needed.
Table
| Field | Current project value | Datasheet / source check | Status |
|---|---|---|---|
| Manufacturer | Infineon | Infineon Technologies AG | OK |
| MPN | IM818LCCXKMA1 | IM818LCCXKMA1 | OK |
| Product family | Discrete Semiconductor Modules / CIPOS MAXI | CIPOS Maxi IM818 intelligent power module | OK |
| Designator Prefix | IC | Reasonable for module part | OK |
| Datasheet URL | Present | Official Infineon URL | OK |
| Package name | Not explicitly stored as a project property | DIP 36x23D in datasheet | Missing metadata |
| Pin count | 24 terminals in project | 24 pins in datasheet | OK |
| Description | Not surfaced as a detailed project property | 1200 V 3-phase intelligent power module with integrated gate driver | Missing metadata |
Table
| Item | Project status | Check |
|---|---|---|
| Schematic symbol | Present | 24 terminals present |
| PCB footprint | Present | 24 pads present |
| 3D model | Present | Present |
| Pad count vs datasheet pin count | 24 vs 24 | OK |
Table
| Parameter | Value |
|---|---|
| Device | IM818-LCC / IM818LCCXKMA1 |
| Topology | 3-phase inverter intelligent power module |
| IGBT / diode rating | 1200 V |
| DC link voltage | 900 V nominal max, 1000 V surge |
| Output current | ±20 A at TC = 25°C, ±15 A at TC = 80°C |
| Pulsed current | ±24 A |
| Isolation test | 2500 V RMS, 1 min |
| Junction temperature | -40°C to 150°C |
| Case temperature | -40°C to 125°C |
| Package | DIP 36x23D |
| External pins | 24 |
The project has the correct count of 24 terminals, but the right-side terminal mapping does not match the datasheet starting at pin 14.
Datasheet pin mapping vs project

| 4 | VB(V) | VB(V) | OK |

| 11 | LIN(V) | LIN(V) | OK |
| 12 | LIN(W) | LIN(W) | OK |
| 13 | VDD | VDD | OK |
| 14 | RFE | VFO | Mismatch |
| 15 | ITRIP | ITRIP | OK |
| 16 | VSS | VSS | OK |
| 17 | VTH | NW | Mismatch |
| 18 | NW | NV | Mismatch |
| 19 | NV | NU | Mismatch |
| 20 | NU | W | Mismatch |
| 21 | W | V | Mismatch |
| 22 | V | U | Mismatch |
| 23 | U | P | Mismatch |
| 24 | P | NC | Mismatch |
Table
| Issue | Impact |
|---|---|
| Pin 14 is labeled VFO, but datasheet says RFE | Symbol pin name mismatch |
| Datasheet pin 17 VTH is missing from the project | Missing terminal / thermistor pin not represented |
| Pins 18-24 appear shifted by one position | Symbol-to-datasheet mismatch likely propagates to footprint mapping |
| Project includes NC at pin 24, but datasheet says pin 24 is P | Incorrect terminal assignment |
| Package metadata is not explicitly stored as DIP 36x23D | Missing part metadata |
| Pin descriptions are not populated in the visible terminal properties | Missing descriptive metadata |
Table
| Area | Result |
|---|---|
| MPN / manufacturer / datasheet link | Good |
| Pin count | Good |
| Symbol terminal names and numbering | Not correct |
| Footprint pad count | Good |
| Footprint pad-to-pin semantic confidence | Needs verification after symbol fix |
| Metadata completeness | Partial |
The big concern is that the project currently looks correct only through pin 13. From pin 14 onward, the terminal naming diverges from the datasheet, which strongly suggests the symbol and likely the footprint pin labeling are not trustworthy until corrected.
If you want, I can next:
- fix the terminal names/numbers to match the datasheet,
- add missing metadata like package/description,
- and help verify the footprint pad numbering against the datasheet pinout.
