📌 Product Overview
💡 The XL-2106PDC is a miniature surface-mount phototransistor encapsulated in a black colloid, specifically designed to detect infrared light while minimizing interference from visible ambient sources.
📏 Housed in a compact 2.1x0.55x1.0mm package, this component is engineered for high-density SMT automated assembly. Its primary design focus is serving as a reliable signal receiver in infrared data transmission and optical switching circuits.
⚙️ Typical Applications
Based on the component's spectral sensitivity (880nm/940nm) and fast response times (Tr/Tf ≤ 15μs), the XL-2106PDC is suitable for the following scenarios:
- Infrared Remote Control: Receiving signals for consumer electronics.
- Industrial Automation: Optical counters, photoelectric switches, and thermal imaging integration.
- Smart Metering: Utility data transmission via infrared pulses.
- Robotics: Intelligent cars and obstacle detection systems.
- Medical Devices: Non-invasive monitoring equipment requiring precise light sensing.

📦 Package, Dimensions & Assembly Notes
👇 The physical footprint and handling requirements must be strictly observed during PCB layout and assembly.
- Dimensions: The body measures 2.1mm (L) x 0.55mm (W) x 1.0mm (H). Unspecified tolerances are ±0.25mm.
- Packaging: EIA standard compliant tape and reel format.
- Moisture Sensitivity: Classified as MSL 3. Components must be baked prior to reflow if exposed to ambient moisture beyond the specified floor life.
- Soldering Profile: Suitable for both leaded and lead-free reflow processes. The maximum recommended peak temperature is 240±5°C for a maximum of 6 seconds to prevent thermal degradation of the epoxy.
- Cleaning: Alcohol is recommended for post-solder cleaning (<50°C for 30s). Ultrasonic cleaning power should not exceed 300W.
📈 Sourcing & Supply Considerations
🚀 When integrating the XL-2106PDC into your BOM, consider the following supply chain factors:
- MSL Compliance: Verify storage conditions at the distributor level to ensure MSL 3 standards have been maintained; improper storage can lead to "popcorning" during reflow.
- Cross-Reference: While the model number appears generic, confirm the mechanical footprint matches existing land patterns to avoid assembly line tweaks.
- Authenticity: Source from channels that can certify ROHS compliance and provide full traceability.
❓ Frequently Asked Questions
Q: What is the peak wavelength sensitivity of the XL-2106PDC?A: The device exhibits peak sensitivity at 880nm (Typical). However, it provides higher photocurrent output (Min 500µA) at 940nm with 1mW/cm² irradiance, making it highly effective for standard 940nm infrared remote controls.
Q: Can this component be used for outdoor applications?A: While the operating temperature range (-40°C to +85°C) allows for outdoor use, the black colloid is designed to minimize visible light interference. However, direct exposure to intense UV sunlight over extended periods may degrade the epoxy resin unless specifically rated for outdoor UV resistance.
Q: What are the specific recommendations for manual soldering?A: Manual soldering should be restricted to repair work only. Use a soldering iron with power less than 30W. The tip temperature must remain below 300°C, and contact time should not exceed 3 seconds per terminal.
Q: How should I handle the tape and reel packaging to prevent moisture damage?A: Since the XL-2106PDC has a Moisture Sensitivity Level (MSL) of 3, it should be stored in a dry cabinet (<10% RH). If the moisture barrier bag is exposed to the factory floor for more than 168 hours (depending on specific IPC standards), baking is required before reflow soldering.
Q: Is this component AEC-Q102 qualified for automotive use?A: The provided datasheet does not explicitly mention AEC-Q102 qualification. While it lists industrial control and robotic applications, strict automotive designs require explicit certification confirmation from the manufacturer.
