TL431ACL5T

STMicroelectronics · Voltage References · SOT-23-5

TL431ACL5T from STMicroelectronics, in a SOT-23-5. 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 Anode power_in Anode terminal; connection to high-side supply voltage (operating voltage Vref to 36 V relative to cathode).
2 NC unconnected No connect; unused internal connection.
3 Ref input Reference input pin for voltage divider feedback network that programs the regulated output voltage (reference input current -0.05 to +10 mA, absolute maximum per Table 1).
4 NC unconnected No connect; unused internal connection.
5 Cathode output Cathode terminal; regulated reference output point where the device sinks current from anode with capability of 1 to 100 mA (sink current per Table 2, page 4).

CAD (KiCad official)

  • Symbol: TL431ACL5T
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tl431acl5t-etched.step / tl431acl5t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl431acl5t.step / tl431acl5t.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (22 pp, sha256 d174b1869a9d426d, retrieved 2026-09-29, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
