**STMicroelectronics** · Voltage Reference · SOT-23-3

TS4041DILT-1.2 from STMicroelectronics, in a SOT-23-3. 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 | Cathode | passive | Shunt reference cathode that sets the 1.225V output (Vk), with operating current from 65µA minimum to 12mA maximum and reverse breakdown current limited to 20mA absolute maximum. |
| 2 | Anode | passive | Anode of the shunt reference, the return/ground side of the device, with forward current limited to 10mA absolute maximum. |
| 3 | NC | unconnected | This pin must be left floating or connected to pin 2 (anode). |
