TP431C124C6-1 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 | input | Cathode (K) terminal of the shunt reference. Sinks the regulated current; Vka is set by the external R1/R2 divider from Vref (1.24 V) to 18 V max. Continuous cathode current range 0.1-100 mA (absolute max −100 to +150 mA). |
| 2 | NC | unconnected | No connection. Note on datasheet: pins 2, 4, 5 are attached to substrate and must be connected to ANODE or left open. |
| 3 | REF | input | Reference input to the internal error amplifier. Compared against internal 1.24 V bandgap; regulation forces Vref across R2 of the external divider. Typical reference input current 0.7 µA (max 4 µA). |
| 4 | NC | unconnected | No connection. Substrate pin - must be connected to ANODE or left open (see datasheet note on page 1). |
| 5 | NC | unconnected | No connection. Substrate pin - must be connected to ANODE or left open (see datasheet note on page 1). |
| 6 | ANODE | power_in | Anode (A) terminal of the shunt reference - the ground/return reference for the device. All voltage values in the datasheet are referenced to this pin. |
