RS432BYSF3 from Jiangsu RUNIC Tech, 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 pin. Threshold input relative to the common anode; the internal amplifier regulates the cathode so that VREF (≈2.5V) appears between REF and Anode. Typical reference input current 1.5µA (max 4µA). |
| 2 | CATHODE | input | Cathode (shunt current/voltage input). Recommended VKA from VREF up to 36V, continuous cathode current 0.5 to 100mA. Acts as the regulated shunt terminal, sinking current to maintain the programmed voltage. |
| 3 | ANODE | power_in | Anode / common pin, normally connected to ground. All voltages in the device specifications are with respect to this pin. |
