PC3H4B

AOTE · Transistor, Photovoltaic Output Optoisolators · SSOP-4

PC3H4B from AOTE, 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 One terminal of the input LED, which the datasheet rates for forward current IF = ±50 (printed with unit 'A', most likely mA), so the LED is driven with either polarity via this pin and pin 2.
2 Cathode/Anode passive Other terminal of the input LED, paired with pin 1 for the ±IF drive, with forward voltage VF typically 1.2 V and maximum 1.4 V at IF = ±20 mA.
3 Emitter passive Phototransistor emitter, with emitter-collector voltage rated VECO 7 V and emitter-collector breakdown BVECO of at least 7 V at IE = 10 µA.
4 Collector output Phototransistor collector, rated for collector-emitter voltage VCEO 80 V, with collector current IC printed as 50 (unit 'A', most likely mA) and collector power PC 150 (unit 'W', most likely mW).

CAD (KiCad official)

  • Symbol: PC3H4B
  • 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: pc3h4b-etched.step / pc3h4b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pc3h4b.step / pc3h4b.glb are the bare package body.

Provenance

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

  • Datasheet: AOTE datasheet (12 pp, sha256 3c3bf5b24dfe4d67, retrieved 2026-10-09, 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: 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).
