TLV431BH6TA

Diodes Incorporated · Voltage References · SOT-363

TLV431BH6TA from Diodes Incorporated, 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 is the shunt current sink, with cathode voltage limited to VREF up to 18V and recommended cathode current of 0.1mA to 15mA.
2 N/C unconnected Die-attached pin that must be left floating or connected to pin 6 per the SC70-6 layout note.
3 REF input Reference input that the regulator holds at VREF of 1.24V, with reference input current limited to -0.05 to +3 mA absolute maximum.
4 NC unconnected Not connected; the datasheet states no electrical function or limit for this pin.
5 N/C unconnected Die-attached pin that must be left floating or connected to pin 6 per the SC70-6 layout note.
6 ANODE passive Anode is the reference node for all voltage ratings, with ESD ratings of 4kV HBM, 400V MM and 1kV CDM.
