4N25

Everlight Elec · Transistor, Photovoltaic Output Optoisolators · DIP-6

4N25 from Everlight Elec, 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 Infrared emitting diode anode; the input is rated for 60 mA forward current (1 A peak for 10 µs) and 6 V reverse voltage.
2 Cathode passive Infrared emitting diode cathode; the input is rated for 60 mA forward current (1 A peak for 10 µs) and 6 V reverse voltage.
3 NC unconnected No connection; the datasheet lists this pin as not connected.
4 Emitter passive Phototransistor emitter; the output is rated for 80 V collector-emitter voltage (VCEO) and 7 V emitter-collector voltage (VECO).
5 Collector passive Phototransistor collector; the output is rated for 80 V collector-emitter voltage (VCEO) and 80 V collector-base voltage (VCBO).
6 Base passive Phototransistor base terminal; the datasheet gives no separate base-pin rating, only the 7 V emitter-base voltage (VEBO) limit.

CAD (KiCad official)

  • Symbol: 4N25
  • Footprint: Package_DIP:DIP-6_W7.62mm
  • 3D model: DIP-6 (KiCad packages3D, STEP)
  • 3D model files: 4n25-etched.step / 4n25-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 4n25.step / 4n25.glb are the bare package body.
