# MOC8050M

**onsemi** · Transistor, Photovoltaic Output Optoisolators · DIP-6

MOC8050M from onsemi, in a DIP-6. 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 | passive | Anode of the gallium arsenide infrared emitting diode; LED forward current is limited to 60 mA DC and reverse input voltage to 3 V (absolute maximum ratings). |
| 2 | CATHODE | passive | Cathode of the gallium arsenide infrared emitting diode, which drives the darlington phototransistor optically; LED forward current is limited to 60 mA DC. |
| 3 | N/C | unconnected | No internal connection; the photodarlington has no base connection on this device. |
| 4 | EMITTER | passive | Emitter of the silicon darlington phototransistor; emitter-collector breakdown is 5 V minimum at IE = 100 µA. |
| 5 | COLLECTOR | passive | Collector of the silicon darlington phototransistor; collector-emitter voltage is 80 V maximum for MOC8050M and continuous collector current is 150 mA. |
| 6 | N/C | unconnected | No internal connection; the photodarlington has no base connection on this device. |

## CAD (KiCad official)

- Symbol: `MOC8050M`
- Footprint: `Package_DIP:DIP-6_W7.62mm`
- 3D model: DIP-6 (KiCad packages3D, STEP)
- 3D model files: `moc8050m-etched.step` / `moc8050m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `moc8050m.step` / `moc8050m.glb` are the bare package body.
