Jaycar BP104 Type Infrared Photodiode – 950nm Sensitivity, 20ns Response Time

Your IR receiver needs to be fast enough for the job. This BP104-type photodiode hits 950nm peak sensitivity with a ±60° half-angle and a 20ns rise/fall time at 5V. Small square body, flag on the cathode leg so you don't wire it backwards at 7pm. Drops into breadboard or PCB alike

• Peak sensitivity at 950nm – pairs with standard 940/950nm IR emitters
• ±60° half-angle for generous receiving window
• 20ns rise and fall time at 5V – fast enough for line-following and object detection
• 330mV open-circuit voltage, compact square package
• Cathode marked with flag on leg – no guessing under the bench light
