IR4428STRPBF-JSM

JSMSEMI · Isolators - Gate Drivers · SOP-8

IR4428STRPBF-JSM from JSMSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connection. Leave floating or tie to ground.
2 INA input Logic input for channel A (non-inverting). CMOS/TTL compatible input threshold; drives output OUTA.
3 INB input Logic input for channel B (non-inverting). CMOS/TTL compatible input threshold; drives output OUTB.
4 GND power_in Device ground return for logic and output stage.
5 OUTB output Gate driver output B. Sources up to 1.5A and sinks up to 2.3A peak; drives MOSFET gate. Non-inverting with respect to INB.
6 VCC power_in Supply voltage input. Operating range 6V to 20V; bypass with a low-ESR ceramic capacitor placed close to the pin.
7 OUTA output Gate driver output A. Sources up to 1.5A and sinks up to 2.3A peak; drives MOSFET gate. Non-inverting with respect to INA.
8 NC unconnected No connection. Leave floating or tie to ground.

Two STEP files. Same geometry, different body top:

File Size Use it when
ir4428strpbf-jsm.step 122 KB You want the bare part, or you mark your own boards.
ir4428strpbf-jsm-etched.step 3.0 MB You want the part with IR4428STRPBF-JSM already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 758 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: JSMSEMI datasheet (9 pp, sha256 a59758b68c128f47, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
