Frequently Asked Questions
Q: What is the difference between the BPW34 and BPW34S photodiode versions?
A: The BPW34 is a through-hole DIP-2 package photodiode designed for standard plug-in PCB installation, while the BPW34S is its surface-mount (SMD-2) equivalent. Both share the same silicon PIN photodiode technology, spectral response range, and sensitivity characteristics — the difference is purely in the physical package and mounting method. This 5-piece set includes both variants so you can choose whichever suits your circuit board design.
Q: What wavelengths does the BPW34 / BPW34S photodiode respond to?
A: The BPW34 and BPW34S silicon PIN photodiodes offer a wide spectral response that covers ultraviolet (UV) through visible light and into the infrared (IR) range. They are particularly well-suited to infrared receiver circuits, remote-control systems, optical communication setups, and ambient light sensing applications.
Q: Are these photodiodes compatible with Arduino or Raspberry Pi projects?
A: Yes! The BPW34 / BPW34S photodiodes are widely used in DIY electronics projects, including Arduino and Raspberry Pi builds. Their high sensitivity and broad spectral response make them excellent for light detection circuits, IR receivers, and optical sensor experiments. The DIP-2 through-hole version is especially easy to insert directly into a breadboard for prototyping.
Q: Are these photodiodes RoHS compliant?
A: Yes. The BPW34 / BPW34S photodiodes are manufactured using RoHS-compliant materials, meaning they are free from hazardous substances such as lead, mercury, and cadmium — making them safe for use in modern electronics manufacturing and environmentally responsible projects.
