ZXLD1356ET5TA from Diodes Incorporated, in a TSOT-23-5. 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 | LX | output | Drain of internal NDMOS switch. Switching node connecting to the external inductor for the step-down (buck) LED driver topology. Rated to 60V (65V for 0.5 sec), switch on-resistance typically 0.5 Ω at 0.55 A. |
| 2 | GND | power_in | Ground (0V) reference for the device. |
| 3 | ADJ | input | Multi-function on/off and brightness control pin. Leave floating for nominal operation (VADJ = VREF = 1.25V, IOUTnom = 0.2V/RS). Drive below 0.2V to turn output off; DC voltage between 0.3V and 2.5V adjusts output current from 24% to 200% of IOUTnom; also accepts PWM for dimming, or a capacitor to ground for soft-start (~0.2ms/nF). |
| 4 | ISENSE | input | LED current sense input. Connect sense resistor RS from this pin to VIN to define nominal average output current IOUTnom = 0.2V/RS (RS min = 0.36 Ω with ADJ open). Mean sense threshold voltage VSENSE = 200 mV typ. |
| 5 | VIN | power_in | Input supply voltage, 6V to 60V (65V for 0.5 sec). Decouple to ground with a 4.7µF or larger X7R ceramic capacitor placed close to the device. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 505 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
