Dual PIN Photodiode

Si PIN Photodiode Array PDCA02-601

The Bee Photon PDCA Series is a precision-engineered Dual PIN Photodiode designed for high-end industrial sensing. Unlike standard single-element detectors, this silicon-based device features a segmented array structure (PD A and PD B), making it the perfect solution for differential sensing and background suppression optical switches. With a wide spectral response from 350nm to 1060nm, it ensures versatile performance across visible and near-infrared wavelengths.

Dual PIN Photodiode

Performance & Reliability
Engineers choose the PDCA Series for its superior signal integrity. This Dual PIN Photodiode delivers industry-leading specifications, including ultra-low dark current (Max 10pA) and low junction capacitance. These features minimize noise interference and guarantee a fast response time (Typ. 0.04μs), which is critical for high-speed automation lines. The component is housed in a durable plastic package that supports lead-free reflow soldering, streamlining your surface mount assembly process.

Target Applications
Optimized for precision and speed, the PDCA Series Dual PIN Photodiode is widely integrated into:

  • Optical Switches: specifically for background suppression to detect objects regardless of color or background.
  • Position Sensing: utilizing the segmented array to provide accurate alignment feedback.
  • Industrial Automation: functioning as a reliable photo sensor in robotics and conveyor systems.
