NTR4502PT1G from onsemi, 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 of the P-channel MOSFET, with gate-to-source voltage rated at ±20 V (VGS). |
| 2 | Source | passive | Source of the P-channel MOSFET, with source current (body diode) rated at −1.25 A (IS). |
| 3 | Drain | passive | Drain of the P-channel MOSFET, with drain-to-source voltage rated at −30 V (VDSS) and continuous drain current of −1.13 A at TA = 25°C steady state (ID), or −1.95 A for t < 10 s. |
