ZR431F01TA-TP from TECH PUBLIC, 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. Internal error amplifier compares this pin against the internal 2.5 V bandgap; when VREF ≥ 2.5 V (typ), the cathode sinks current. Reference input current I(REF) ≈ 0.7 µA typ, 4 µA max; max continuous input current 10 mA. |
| 2 | CATHODE | passive | Cathode (K) terminal of the shunt regulator. Sinks the regulated current when VREF pin reaches the internal reference. Absolute max VKA = 36 V, continuous IKA range −100 to +150 mA, operating IKA 1-100 mA, dynamic impedance ZKA ≈ 0.15 Ω typ. |
| 3 | ANODE | passive | Anode (A) terminal of the shunt regulator; typically tied to the system ground/return. All device voltages are referenced to the anode per the datasheet's absolute maximum ratings notes. |
