**KEC Semicon** · MOSFETs · SOT-23

KTK5132S-RTK from KEC Semicon, 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 | SOURCE | passive | Source terminal of the N-channel enhancement-mode MOSFET; the datasheet rates the device at VDS 30 V and VGSS ±20 V with respect to this pin. |
| 2 | GATE | input | Gate terminal with a maximum gate-source voltage of ±20 V, a gate threshold of 0.5 to 1.5 V, and gate leakage IGSS of ±1 µA max at VGS = ±16 V. |
| 3 | DRAIN | passive | Drain terminal rated for 30 V drain-source voltage and 100 mA DC drain current, with 200 mW maximum drain power dissipation. |
