**CRMICRO** · MOSFETs · DFN-8(5x6)

CRSM038N10N4 from CRMICRO, in a DFN-8(5x6). 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 | S | passive | Source pin 1 (S1 in the package view); source terminal, with VDS rated 100V and continuous ID of 100A at TC=25°C. |
| 2 | S | passive | Source pin 2 (S2 in the package view); source terminal, tied to the same source as pins 1 and 3. |
| 3 | S | passive | Source pin 3 (S3 in the package view); source terminal, tied to the same source as pins 1 and 2. |
| 4 | G | input | Gate pin (G4 in the package view); gate-source voltage limited to ±20V, with a typical threshold VGS(th) of 3V at ID=250uA. |
| 5 | D | passive | Drain pin 5 (D5 in the package view); drain terminal, connected to the exposed drain pad, with VDS rated 100V. |
| 6 | D | passive | Drain pin 6 (D6 in the package view); drain terminal, connected to the exposed drain pad. |
| 7 | D | passive | Drain pin 7 (D7 in the package view); drain terminal, connected to the exposed drain pad. |
| 8 | D | passive | Drain pin 8 (D8 in the package view); drain terminal, connected to the exposed drain pad, with pulsed drain current up to 400A. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
