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. |
