Vishay Intertech · Transistor, Photovoltaic Output Optoisolators · DIP-6
TCDT1102G from Vishay Intertech, 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 | A(+) | passive | Anode of the gallium arsenide infrared-emitting diode; the absolute maximum forward current is 60 mA and the reverse voltage is 5 V. |
| 2 | C(-) | passive | Cathode of the infrared-emitting diode; the reverse voltage rating is 5 V maximum. |
| 3 | NC | unconnected | No connection. |
| 4 | E | passive | Emitter of the phototransistor; the emitter-collector voltage VECO is 7 V maximum. |
| 5 | C | passive | Collector of the phototransistor; the collector-emitter voltage VCEO is 32 V maximum and the collector current IC is 50 mA maximum. |
| 6 | NC | unconnected | No connection; the phototransistor base is not connected, which provides noise immunity. |
