# BCR430U

**Infineon Technologies** · LED Drivers · SOT-23-6

BCR430U from Infineon Technologies, in a SOT-23-6. 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 | N.C. | unconnected | Not connected; the datasheet gives no electrical function for this pin. |
| 2 | GND | power_in | IC ground and thermal connection to the heat spreader on the PCB. |
| 3 | RS | output | Connection of the Rset resistor that sets the LED current; the RS pin voltage is typically 1.20 V with IRS limited to 0 to 0.3 mA. |
| 4 | VS | power_in | Supply voltage input with an operational range of 6 V to 42 V and an absolute maximum of 45 V. |
| 5 | N.C. | unconnected | Not connected; the datasheet gives no electrical function for this pin. |
| 6 | LED | input | Driver pin that controls the LED current, up to 100 mA, with a voltage limit of 0 to 20 V at the LED pin. |

## CAD (KiCad official)

- Symbol: `BCR430U`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `bcr430u-etched.step` / `bcr430u-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bcr430u.step` / `bcr430u.glb` are the bare package body.
