MP3H4B

miracle · Transistor, Photovoltaic Output Optoisolators · SSOP-4

MP3H4B from miracle, in a SSOP-4. 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/Cathode passive AC input LED terminal (two anti-parallel AlGaAs IR emitting diodes); forward current max ±60 mA, forward voltage max 1.4 V at IF=10 mA.
2 Cathode/Anode passive AC input LED terminal (second side of anti-parallel emitters); forward current max ±60 mA, peak forward current ±1 A.
3 Emitter passive Phototransistor emitter; emitter-collector voltage max 6 V.
4 Collector passive Phototransistor collector; collector-emitter voltage max 80 V, collector current max 50 mA.

Key specifications

Parameter Value
Manufacturer miracle
Package SSOP-4
Category Optoisolators
Pins 4

CAD (KiCad official)

  • Symbol: MP3H4B
  • Footprint: Package_SO:SSOP-4_4.4x2.6mm_P1.27mm
  • 3D model: SSOP-4, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.75 mm nominal SSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: mp3h4b-etched.step / mp3h4b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mp3h4b.step / mp3h4b.glb are the bare package body.

Provenance

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

  • Datasheet: miracle datasheet (12 pp, sha256 74a7e0d5a2bae1c4, retrieved 2026-10-09, tier: lcsc)
  • 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).
