# SE2N65

**SINO IC** · MOSFETs · TO-252

SE2N65 from SINO IC, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate. Insulated MOSFET control terminal. VGS(th) = 2.5-4.5 V; absolute maximum VGS = ±30 V; gate-body leakage IGSS = 100 nA max @ VGS = 30 V. Drive with VGS = 10 V for RDS(on) = 3.5 Ω typ. |
| 2 | D | passive | Drain. Power terminal, typically connected to the higher potential in an N-channel high-side/low-side switching topology. BVDSS = 650 V; IDSS = 1 µA max @ VDS = 650 V. Continuous ID = 2 A, pulsed 8 A. Electrically common to the mounting tab. |
| 3 | S | passive | Source. Power/return terminal and reference for VGS. Body diode: VSD = 1.4 V max @ IS = 2 A, trr = 300 ns typ, QRR = 2.2 µC. |

## CAD (KiCad official)

- Symbol: `SE2N65`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `se2n65-etched.step` / `se2n65-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `se2n65.step` / `se2n65.glb` are the bare package body.
