# VN751STR

**STMicroelectronics** · Power Distribution Switches · SO-8

VN751STR from STMicroelectronics, in a SO-8. 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 | GND | power_in | Ground pin, with a maximum DC reverse ground pin current of -200 mA, and the device turns off automatically if this pin is disconnected. |
| 2 | INPUT | input | CMOS-compatible control input with VIL max 1.25 V, VIH min 3.25 V and DC input current rated -1 to +10 mA. |
| 3 | STATUS | output | Open-drain status output with status low voltage max 0.5 V at ISTAT = 1.6 mA and DC status current rated -1 to +10 mA. |
| 4 | NC | unconnected | Not connected pin; the datasheet states no function or limits for it. |
| 5 | VCC | power_in | Supply voltage pin, 5.5 V to 36 V operating with 45 V absolute maximum DC supply voltage, and shared with pins 8 for the supply connection. |
| 6 | OUT | power_out | High-side power output to the load with RDS(on) typ 60 mOhm, current limit 2.7 A to 6.0 A, and reverse DC output current rated -5 A. |
| 7 | OUT | power_out | High-side power output to the load with RDS(on) typ 60 mOhm, current limit 2.7 A to 6.0 A, and reverse DC output current rated -5 A. |
| 8 | VCC | power_in | Supply voltage pin, 5.5 V to 36 V operating with 45 V absolute maximum DC supply voltage, and shared with pin 5 for the supply connection. |

## CAD (KiCad official)

- Symbol: `VN751STR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SO-8 (KiCad packages3D, STEP)
- 3D model files: `vn751str-etched.step` / `vn751str-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `vn751str.step` / `vn751str.glb` are the bare package body.
