MMBTA05LT1G

onsemi · Bipolar (BJT) · SOT-23

MMBTA05LT1G from onsemi, in a SOT-23. 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 BASE input Base terminal of the NPN driver transistor; the datasheet gives no separate pin-level limit, and the device ratings apply (VEBO 4.0 Vdc, IC 500 mAdc continuous).
2 EMITTER passive Emitter terminal of the NPN driver transistor; the datasheet gives no separate pin-level limit, and the device ratings apply (VCEO 60 Vdc for MMBTA05L, IC 500 mAdc continuous).
3 COLLECTOR passive Collector terminal of the NPN driver transistor; the datasheet gives no separate pin-level limit, and the device ratings apply (VCEO 60 Vdc and VCBO 60 Vdc for MMBTA05L, collector current 500 mAdc continuous).

CAD (KiCad official)

  • Symbol: MMBTA05LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbta05lt1g-etched.step / mmbta05lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbta05lt1g.step / mmbta05lt1g.glb are the bare package body.

Provenance

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

  • Datasheet: onsemi datasheet (9 pp, sha256 881fe43b3d4e6102, retrieved 2026-10-09, 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).
