Frequently Asked Questions

Q: What is the difference between BPW34 and BPW34S photodiodes?

A: The BPW34 uses a standard DIP-2 (through-hole) package, making it easy to insert directly into a breadboard or PCB holes. The BPW34S is the SMD-2 (surface-mount) variant of the same component, designed for reflow or hand-soldering directly onto a PCB surface. Both share the same silicon PIN photodiode chip and electrical characteristics.

Q: What wavelength range do these BPW34 photodiodes respond to?

A: These silicon PIN photodiodes feature a wide spectral response covering the ultraviolet through infrared range, with peak sensitivity typically in the near-infrared region — making them especially well-suited for infrared remote control receivers, IR sensing circuits, and light-level detection applications.

Q: Are these photodiodes compatible with Arduino or Raspberry Pi projects?

A: Yes. The BPW34 / BPW34S photodiodes are widely used in DIY electronics and are compatible with Arduino, Raspberry Pi, and other microcontroller platforms. They can be integrated into ambient light sensors, proximity detectors, optical communication circuits, and more with standard supporting components.

Q: Are these components RoHS compliant?

A: Yes. The BPW34 / BPW34S photodiodes meet RoHS environmental standards, meaning they are free from hazardous substances including lead, mercury, and cadmium — making them suitable for environmentally conscious builds and products destined for markets with strict compliance requirements.
