**ETERNAL** · MOSFETs · SOT-23

EN2300 from ETERNAL, in a SOT-23. 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 MOSFET, rated for a gate-source voltage of ±12 V, with gate-body leakage limited to ±100 nA at VGS=±12 V. |
| 2 | Source | passive | Source terminal of the N-channel MOSFET; the datasheet gives no pin-specific limit and lists the device ratings as VDS 20 V and continuous ID 5.4 A. |
| 3 | Drain | passive | Drain terminal of the N-channel MOSFET, rated for a drain-source voltage of 20 V, continuous drain current of 5.4 A and pulsed drain current of 24 A. |
