TP431C249C6 from TECH PUBLIC, in a SOT-363. 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 | Cathode of the adjustable shunt regulator; maximum cathode voltage 36 V and continuous cathode current 1 mA to 100 mA. |
| 2 | NC | unconnected | No connect; attached to substrate and must be connected to ANODE or left open. |
| 3 | REF | input | Reference input, regulated to about 2.495 V (2.483 V to 2.507 V) with reference input current rated 10 mA maximum. |
| 4 | NC | unconnected | No connect; attached to substrate and must be connected to ANODE or left open. |
| 5 | NC | unconnected | No connect; attached to substrate and must be connected to ANODE or left open. |
| 6 | ANODE | passive | Anode of the shunt regulator, the ground-side reference node to which all voltages are referred. |
