SSTA28T116

ROHM Semicon · Darlington Transistors · SOT-23

SSTA28T116 from ROHM Semicon, 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 Emitter passive Emitter of the Darlington NPN pair, with VEBO rated 12 V maximum and collector current IC up to 300 mA.
2 Base passive Base input of the Darlington NPN pair, with a base-emitter turn-on voltage VBE(on) of 1.4 V typical (2.0 V max) at VCE = 5 V, IC = 100 mA.
3 Collector passive Collector of the Darlington NPN pair, with VCES and VCBO rated 80 V maximum and IC up to 300 mA.

Key specifications

Parameter Value
Manufacturer ROHM Semicon
Package SOT-23
Category Triode/MOS Tube/Transistor
Pins 3

CAD (KiCad official)

  • Symbol: SSTA28T116
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ssta28t116-etched.step / ssta28t116-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ssta28t116.step / ssta28t116.glb are the bare package body.

Provenance

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

  • Datasheet: ROHM Semicon datasheet (8 pp, sha256 a780919e7c691516, retrieved 2026-11-02, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-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).
