AS431HANTR-G1

Diodes Incorporated · Voltage Reference · SOT-23

AS431HANTR-G1 from Diodes Incorporated, in a SOT-23. 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 REF input Reference input to the internal error amplifier. Regulation forces this pin to VREF (nominally 2.495V) relative to ANODE. Reference input current is typically 0.7uA (4uA max); maximum allowed IREF is 10mA.
2 CATHODE passive Shunt cathode (K). Sinks current when the REF pin exceeds VREF, clamping VKA. Operating VKA range is VREF to 36V, cathode current 0.5mA to 100mA (Absolute Max VKA = 40V, IKA = -100 to 150mA). Dynamic impedance ZKA = 0.15 Ohm typ.
3 ANODE passive Shunt anode (A), the device's local ground reference. All VREF and VKA voltages are referenced to this pin.
