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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | TSOT-23-5 |+| Category | LED-drv |+| Pins | 5 |++## Ordering variants++- `ZXLD1356ET5TAET5TA`+- `ZXLD1356ET5TADACTC`+- `ZXLD1356ET5TAQESTTC`++## CAD (KiCad official)++- Symbol: `ZXLD1356ET5TA`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: TSOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/ZXLD1356ET5TA.pdf) (29 pp, sha256 `22810b3c3d68a419`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
