TLP621GB-1 from UMW, in a DIP-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 | passive | LED anode of the gallium arsenide infrared emitting diode; the LED reverse current is specified at VR=5V and forward voltage at IF=10mA (typ 1.15V). |
| 2 | Cathode | passive | LED cathode of the infrared emitting diode, returned to the input drive circuit; LED forward current is rated at 50mA maximum in the absolute maximum ratings. |
| 3 | Emitter | passive | Phototransistor emitter on the detector side; the emitter-collector breakdown voltage is 7V minimum at IE=0.1mA. |
| 4 | Collector | passive | Phototransistor collector on the detector side; the collector-emitter breakdown voltage is 55V minimum at IC=0.5mA and collector current is limited to 50mA. |
