PC3H7B

AOTE · Transistor, Photovoltaic Output Optoisolators · SSOP-4

PC3H7B 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	input	LED anode of the input emitter; the datasheet limits forward current IF to 50 (printed as 'A', likely mA), reverse voltage VR to 6 V, and peak pulse forward current IFP to 1000 (1 µs pulse, printed as 'A').
2	Cathode	passive	LED cathode of the input emitter, returning the forward current; the same input ratings apply (IF 50, VR 6 V, IFP 1000 for 1 µs pulses, units as printed).
3	Emitter	passive	Phototransistor emitter on the output side; the datasheet gives emitter-collector voltage VECO 7 V maximum and BVECO of at least 7 V at IE=0.01mA.
4	Collector	passive	Phototransistor collector on the output side; the datasheet gives collector-emitter voltage VCEO 80 V maximum, collector current IC 50 (printed as 'A', likely mA), and total power Ptot 200 (printed as 'W').

CAD (KiCad official)

Symbol: PC3H7B
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: pc3h7b-etched.step / pc3h7b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pc3h7b.step / pc3h7b.glb are the bare package body.

Provenance

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