TLV431BQDCKR from Texas Instruments, in a SC-70-6. 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 | CATHODE | bidirectional | Adjustable shunt regulator cathode with 1.24 V to 6 V output voltage range and ±20 mA absolute maximum continuous current. |
| 2 | Substrate | passive | Substrate terminal connection that must be connected to ANODE or left open. |
| 3 | REF | input | Reference threshold pin accepting external voltage input with ±0.05 mA to 3 mA reference current range. |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
| 6 | ANODE | power_in | Common anode reference terminal, typically connected to ground. |
