AZ431LAZTR-G1 from Diodes Incorporated, in a TO-92-3. 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 | Reference input that sets the output voltage through an external two-resistor divider, with a reference voltage of 1.240 V typical (1.234 V to 1.246 V for the 0.5% grade). |
| 2 | ANODE | passive | Anode terminal of the shunt regulator; cathode current is sunk from the cathode through this terminal, with cathode current limited to 0.1 mA to 100 mA in recommended operation. |
| 3 | CATHODE | passive | Cathode terminal of the shunt regulator, rated for a cathode voltage of 18 V maximum in recommended operation (20 V absolute maximum) and a continuous cathode current of -100 mA to 100 mA absolute. |
