LM385Z-2.5G

onsemi · Voltage References · TO-92

LM385Z-2.5G from onsemi, in a TO-92. 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 N.C. unconnected Not connected; the datasheet lists this lead as no-connect and gives no function for it.
2 Cathode passive Cathode of the two-terminal bandgap voltage reference diode, which for the 2.500 V version has a minimum operating current (IRmin) of 13 µA and a maximum reverse current of 30 mA.
3 Anode passive Anode of the two-terminal bandgap voltage reference diode, which has a maximum forward current of 10 mA.

  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: lm385z-2-5g-etched.step / lm385z-2-5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm385z-2-5g.step / lm385z-2-5g.glb are the bare package body.

Provenance

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

  • Datasheet: onsemi datasheet (11 pp, sha256 9a381b14de69dd6e, retrieved 2026-10-30, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
