CNY173M

onsemi · Transistor, Photovoltaic Output Optoisolators · DIP-6

CNY173M 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 LED anode of the gallium arsenide infrared emitting diode; the datasheet limits continuous forward current to 60 mA (IF, absolute maximum) and peak forward current to 1.5 A (1 µs pulse, 300 pps).
2 CATHODE passive LED cathode of the infrared emitting diode; the datasheet gives a reverse voltage limit of 6 V (VR).
3 NC unconnected No internal connection on this variant.
4 EMITTER passive NPN phototransistor emitter; the datasheet gives an emitter-collector voltage limit of 7 V (VECO).
5 COLLECTOR passive NPN phototransistor collector; the datasheet limits collector-emitter voltage to 70 V (VCEO) and continuous collector current to 50 mA (IC).
6 BASE passive Phototransistor base brought out for this variant (CNY171M/2M/3M/4M), usable with a base-emitter resistor to adjust CTR and switching; the datasheet gives no pin-specific voltage or current limit.

CAD (KiCad official)

  • Symbol: CNY173M
  • Footprint: Package_DIP:DIP-6_W7.62mm
  • 3D model: DIP-6 (KiCad packages3D, STEP)
  • 3D model files: cny173m-etched.step / cny173m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cny173m.step / cny173m.glb are the bare package body.
