AONS66614 Part Review
D_5 while AONS source-down package evidence suggests it may need to be Source. The core pins 1–8 match the datasheet pinout, and the DFN5x6_8L_EP1_P footprint geometry appears mechanically consistent.Passive, SourceInput, GatePassive, DrainPassive, Drain exposed padTable
| Field | Current value | Review |
|---|---|---|
| Project name | AONS66614 | Matches MPN. |
| Description | 60V N-Channel AlphaSGT TM | Matches datasheet meaning; typography differs from AlphaSGT™ only. |
| Manufacturer Part Number | AONS66614 | Matches official part number. |
| Manufacturer Name | Alpha & Omega Semiconductors | Minor naming mismatch: official AOS branding/product page uses Alpha & Omega Semiconductor / AOS. |
| Datasheet URL | IHS mirror URL | A datasheet URL is already set, so I did not change it automatically. For traceability, the preferred official URL is https://www.aosmd.com/sites/default/files/res/datasheets/AONS66614.pdf. |
| Designator Prefix | Q | Appropriate for MOSFET/transistor. |
| Part Type | Not set | Component review warns that Part Type is missing. Should be set to MOSFET / N-channel MOSFET if the part library supports it. |

| 8 | Drain | D_4 | Correct function by name. |
| 9 | Extra footprint exposed/large pad | D_5 | Needs review. The official datasheet pin table only numbers pins 1-8 and does not explicitly define a pin 9. The current CAD model maps the large pad as Drain. However, AOS Source Down DFN5x6 technology documentation says the PCB-side large pad is Source, and AONS-family devices appear to use that source-down package style. Treat the current D_5 exposed-pad assignment as a high-risk mismatch until verified directly from AOS or package-specific ECAD data. |

| 7 | D_3 | Passive or Power | Drain |
| 8 | D_4 | Passive or Power | Drain |
| 9 | S_EP or D_EP pending confirmation | Passive or Power | Exposed pad / large PCB-side pad; electrical net must be verified. |

| Large pad | 4.12 × 4.60 mm | Land pattern shows 4.12/4.60 mm main pad dimensions | Mechanically consistent. |
| Footprint name | AON6482 | AONS66614 | Mechanical reuse may be acceptable, but the name is misleading and may indicate inherited electrical pad mapping from a different MOSFET. |
| Pad 9 net/function | D_5 / Drain in current symbol | Not explicitly numbered in AONS66614 datasheet; source-down package evidence suggests source-side large pad | High-risk electrical assignment to verify/fix. |
D_5. The official AONS66614 datasheet only explicitly defines pins 1-8; AOS source-down DFN5x6 documentation says the large PCB-side pad is Source. This should be verified and likely changed to a source exposed pad if this is the intended AONS source-down package.D_5 to S_EP/S_PAD and map pin 9 to Source.Scope
