Jiangsu RUNIC Tech · Voltage Reference · SOT-23
RS432AXSF3-Q1 from Jiangsu RUNIC Tech, in a SOT-23. 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 | Ref | input | Threshold (reference) input relative to the common anode, set to VREF of 2.488 V to 2.512 V at IKA = 10 mA (0.5% A grade), with reference input current range of -0.05 mA to +10 mA. |
| 2 | Cathode | passive | Shunt current/voltage input; recommended cathode voltage is VREF to 32 V and recommended continuous cathode current is 0.5 mA to 100 mA, with absolute maximum cathode voltage of 37 V and continuous cathode current of -100 mA to +155 mA. |
| 3 | Anode | power_in | Common pin, normally connected to ground; all voltages are specified with respect to the GND pin. |
