This 5mm Water-clear Phototransistor will pick up visible and infrared light and conduct current. When light reaches this high sensitive/fast response time component it's much like current reaching the base of a transistor which allows current to flow from collector to emitter.

Description [Hide]

Because the lens of these phototransistors is clear they are sensitive to both visible and infrared light. Unlike a photodiode, phototransistors do not produce electricity but act more like a switch when light is applied, allowing current to flow through them from collector to emitter. If you are looking for a photodiode we have one available here.

The phototransistor can be used to detect visible light but can also be used with our IR-LED to form a beam breaking spy projects or to detect close range reflections bouncing off a surface.

The short lead (flat side) of the phototransistor is the collector side and the long lead is the emitter.


  • Voltage - Collector Emitter Breakdown (Max) - 30V
  • Current - Collector (Ic) (Max) - 20mA
  • Current - Dark (Id) (Max) - 100nA
  • Wavelength of peak sensitivity: 940nm
  • Wavelength Range: 400-1100nm
  • Mounting Type: Through Hole
  • RoHS compliant

Please Note: A datasheet with dimensions and pin-out is available under the Resources tab.
