TCDT1103G

Vishay Intertech · Transistor, Photovoltaic Output Optoisolators · DIP-6

TCDT1103G 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 diode is rated for a maximum forward current of 60 mA and a maximum reverse voltage of 5 V.
2 C passive Cathode of the gallium arsenide infrared-emitting diode, the return path for the input LED current (forward current limit 60 mA, forward surge current 3 A for tp ≤ 10 µs).
3 NC unconnected Not connected; no internal connection is made to this pin.
4 E passive Emitter of the phototransistor; the emitter-collector voltage VECO is rated at 7 V maximum.
5 C passive Collector of the phototransistor; the collector-emitter voltage VCEO is rated at 32 V maximum and the collector current IC at 50 mA maximum.
6 NC unconnected Not connected; the phototransistor base is intentionally left unconnected to provide noise immunity.
