TLVH431NAQDBZRVL from Nexperia, in a TO-236AB. 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 of the adjustable shunt regulator, nominally Vref of about 1.24 V (1228 to 1252 mV at IK = 10 mA, Tamb = 25 °C for the A-Grade 1 % part), with two external resistors setting the output voltage up to 14 V. |
| 2 | K | passive | Cathode, rated for a cathode-anode voltage VKA up to 14 V and a cathode current IK from 0.08 mA to 70 mA (minimum cathode current 80 µA maximum at VKA = Vref). |
| 3 | A | passive | Anode, the common terminal for the cathode-anode voltage VKA, which is limited to 14 V. |
