AS431AZTR-E1 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 via a resistor divider, with VREF of 2.5V typical (2.487V to 2.512V for the 0.5% grade) and reference current of 0.7µA typical. |
| 2 | ANODE | power_in | Anode terminal, connected to ground in the typical application circuits. |
| 3 | CATHODE | passive | Cathode terminal that sinks 1mA to 100mA in regulation, with a recommended maximum cathode voltage of 36V and an absolute maximum of 40V. |
