Products Description
3mm Flat Top Photodiode PD – 400-1100nm IR Receiver Diode for Photoelectric Sensors
This 3mm flat top photodiode is built for one job: reliable light detection in compact photoelectric sensor designs. We use a larger chip than standard PDs on the market - that's why it delivers consistent output even when ambient light changes, and why we use it in our own sensor module assemblies.

Why It Works for Your Design
No signal jitter: The large chip design reduces noise and keeps output stable across temperature changes - critical for proximity sensors and slot sensors that run 24/7.
Fast enough for high-speed lines: 10 ns response time won't bottleneck your encoder or high-speed counting circuits.
Easy to mount: The flat top profile and standard lead spacing fit most photoelectric receiver module layouts without extra tooling.
Typical Applications
Photoelectric sensor receivers (slot, diffuse, through-beam types)
Industrial automation light detection
Position and speed sensing in machinery
Optical encoder modules
FAQ:
1. What is the spectral range of this 3mm flat top photodiode?
Answer:
It covers 400–1100 nm, which includes visible light and near‑infrared wavelengths. This makes it suitable for both visible and IR‑based photoelectric sensor applications.
2. Can this photodiode be used with an 850nm or 940nm IR LED?
Answer:
Yes. The 400–1100nm response range ensures high sensitivity to common industrial IR wavelengths such as 850nm and 940nm, making it a reliable receiver for through‑beam and diffuse sensors.
3. What is the response time of this PD, and why does it matter?
Answer:
The typical response time is 10 nanoseconds. This fast switching speed prevents signal delay in high‑speed counting, encoder, or positioning systems used in industrial automation.
4. Is this photodiode suitable for outdoor or high‑ambient‑light environments?
Answer:
It performs well in typical industrial environments. The larger chip design improves signal stability under fluctuating ambient light, though additional optical filtering may be required for direct sunlight exposure.
5. What is the lead spacing and package type?
Answer:
It uses a 3mm flat top through‑hole package with a 2.54 ± 0.1 mm lead spacing, which fits standard PCB layouts for photoelectric sensor receiver modules.
