TLV431AH6TA

Diodes Incorporated · Voltage Reference · SC-70-6

TLV431AH6TA from Diodes Incorporated, in a SC-70-6. 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 shunt regulator; voltage VKA is VREF to 18V recommended (20V absolute max) with 0.1mA to 15mA recommended cathode current.
2 N/C unconnected No connect, die-attached pin that must be left floating or connected to ANODE (pin 6).
3 REF input Reference (feedback) input of the 1.24V shunt regulator, connected to the external R1/R2 divider, with reference input current range -0.05 to +3mA.
4 NC unconnected No connect pin.
5 NC unconnected No connect, die-attached pin that must be left floating or connected to ANODE (pin 6).
6 ANODE power_in Anode of the shunt regulator, connected to ground; all datasheet voltages are referenced to this pin.
