TL431AIDCKR-TP

TECH PUBLIC · Voltage Reference · SOT-363

TL431AIDCKR-TP 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 -100 to +150 mA.
2 NC unconnected No connect; attached to substrate and must be connected to ANODE or left open.
3 REF input Reference input that sets the output voltage via an external divider, with Vref typically 2.495 V and reference input current range up to 10 mA.
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, normally connected to ground; all voltage ratings are referenced to the anode.
