TLVH431NAMQDBZRVL

Nexperia · Voltage Reference · TO-236AB

TLVH431NAMQDBZRVL from Nexperia, in a TO-236AB. 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 K passive Cathode; the cathode-anode voltage VKA is specified up to 14 V and the cathode current IK from 0.08 mA to 70 mA.
2 REF passive Reference input; the reference voltage Vref is 1222 mV to 1258 mV for standard grade and 1228 mV to 1252 mV for A-grade at IK = 10 mA, and the reference current Iref is limited to 3 mA.
3 A passive Anode; the cathode-anode voltage VKA is referenced to this pin and the minimum cathode current IK(min) is 55 µA to 80 µA.
