**Leiditech** · MOSFETs · SOT-523

NTA7002NT1G from Leiditech, in a SOT-523. 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 | GATE | input | Gate terminal of the N-channel enhancement MOSFET, with gate-source voltage rated at ±20 V (VGS). |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET, referenced by the 30 V drain-source breakdown rating [V(BR)DSS min 30 V at VGS = 0 V, ID = 10 µA]. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET, rated for VDS of 30 V and a drain current of 150 mA per the device summary table, with power dissipation of 0.15 W. |

## CAD (KiCad official)

- Symbol: `NTA7002NT1G`
- Footprint: `Package_TO_SOT_SMD:SOT-523`
- 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `nta7002nt1g-etched.step` / `nta7002nt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `nta7002nt1g.step` / `nta7002nt1g.glb` are the bare package body.
