Part Data Review and Validation
Thought for 5 mins 11 sec
I audited the part using a datasheet-first check: exact pin count, exact pin numbers, and the datasheet as the source of truth for symbol/terminal validation
Review Summary
Table
| Category | Current project | Datasheet / official source | Status |
|---|---|---|---|
| MPN | IMZC120R040M2HXKSA1 | IMZC120R040M2HXKSA1 | Match |
| Manufacturer | Infineon | Infineon | Match |
| Datasheet URL | DigiKey mirror already set | Official Infineon PDF also exists: https://www.infineon.com/assets/row/public/documents/60/49/infineon-imzc120r040m2h-datasheet-en.pdf | Acceptable, but not canonical |
| Pin count | 4 terminals | 4 pins | Match |
| Pin names | Drain / Source / Kelvin Sense / Gate | Drain / Source / Kelvin sense contact / Gate | Match |
| Package family | Project description says PG-TO247-4-17 | Official package code is PG-TO247-4-U07, product page shows PG-TO247-4 / TO-247-4 HC 8.8 mm | Mismatch |
| Designator prefix | Q | MOSFET/transistor class => Q | Match |
Table
| Spec | Value |
|---|---|
| Device type | CoolSiC 1200 V SiC MOSFET G2 |
| VDSS | 1200 V |
| RDS(on) | 40 mOhm typ @ VGS = 18 V, 25 C |
| Continuous drain current | 48 A @ Tc = 25 C, 34 A @ Tc = 100 C |
| Peak drain current | 170 A |
| Power dissipation | 218 W @ Tc = 25 C |
| Junction temperature | -55 C to 175 C |
| Storage temperature | -55 C to 150 C |
| Short-circuit withstand time | 2 us |
The schematic terminals align correctly with the datasheet pinout:
Table
| Datasheet pin | Project terminal | Status |
|---|---|---|
| Pin 1: Drain | DRAIN | Match |
| Pin 2: Source | SOURCE | Match |
| Pin 3: Kelvin sense contact | KELVIN_SENSE_CONTACT | Match |
| Pin 4: Gate | GATE | Match |
- The layout has 4 pads, and pad names correspond to the same four terminals:
- So the pad count and logical pad naming are consistent with the datasheet.
- The project metadata, however, does not use the canonical package code. The datasheet calls this PG-TO247-4-U07, while the current description says PG-TO247-4-17.
Table
| Item | Issue | Recommendation |
|---|---|---|
| Package metadata | Description uses PG-TO247-4-17, but official package code is PG-TO247-4-U07 | Update description and/or Package or Case Code property to PG-TO247-4-U07 |
| Datasheet URL quality | URL is present, so no required update under your rule, but it points to a DigiKey mirror | Optional: normalize to the official Infineon PDF URL |
| Pin typing | All four terminals have Pin Type = Unspecified | Set GATE = Input, DRAIN = Passive or Power, SOURCE = Passive/Power, KELVIN_SENSE_CONTACT = Passive |
| Pin descriptions | No per-pin descriptions are set | Add short descriptions from datasheet: Drain, Source, Kelvin sense contact, Gate |
| Project description | Current text is mostly raw parametrics | Rewrite to a cleaner part-style summary |
- Good: MPN, manufacturer, pin count, pin numbering, terminal names, and 4-pad footprint structure all line up with the datasheet.
- Needs cleanup: package code metadata, terminal pin types, and terminal descriptions.
- No automatic datasheet update was needed because a datasheet URL was already set.
If you want, I can clean this up next by:
- updating the package metadata to PG-TO247-4-U07
- setting the terminal pin types/descriptions
- rewriting the project description into a proper library-quality summary
