TP431C124C6

TECH PUBLIC · Voltage Reference · SOT-363

TP431C124C6 from TECH PUBLIC, in a SOT-363. 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 CATHODE passive Cathode (K) of the shunt reference. Sinks the regulated cathode current IKA (0.1-100 mA operating, 18 V absolute max VKA). Tied to the output node in shunt/series-regulator applications.
2 NC unconnected No internal connection. Attached to substrate; per datasheet note must be connected to ANODE or left open.
3 REF input Reference input (feedback) pin. Internal error amplifier regulates so that V(REF) ≈ Vref (typ 1.24 V). Driven by the R1/R2 divider from CATHODE to ANODE. Reference input current IREF ≈ 0.7 µA typ.
4 NC unconnected No internal connection. Attached to substrate; per datasheet note must be connected to ANODE or left open.
5 NC unconnected No internal connection. Attached to substrate; per datasheet note must be connected to ANODE or left open.
6 ANODE passive Anode (A) of the shunt reference. All voltage measurements are referenced to this pin; typically tied to circuit ground in shunt/series-regulator applications.
