ES138KR from ElecSuper, in a SOT-723. 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 VGS of ±20 V (absolute maximum), with 10 V and 4.5 V RDS(on) specified. |
| 2 | Source | passive | Source terminal of the N-channel MOSFET, the reference for the gate-source voltage (VGS). |
| 3 | Drain | passive | Drain terminal of the N-channel MOSFET, rated 60 V drain-source breakdown (BVDSS) and 0.25 A continuous drain current. |
