📦 Package, Dimensions & Assembly Notes
- Dimensions: The outline measures 3.2mm (L) x 2.7mm (W) x 1.0mm (H). All dimension tolerances are ±0.30mm unless specified.
- Packaging: EIA standard tape and reel packaging for automated assembly.
- MSL Level: 🌡️ The component is classified as Moisture Sensitivity Level (MSL) 3.
- Floor Life: 168 hours.
- Requirement: Baking is required if the specified floor life is exceeded before reflow soldering.
- Assembly: 🔒 Do not apply stress to the LED during heating. Reflow soldering should be performed once to prevent thermal degradation.
🚢 Sourcing & Supply Considerations
- Supply Chain: Available in TR8 (Tape and Reel) format, the XL-PD15-22C supports high-volume automated SMT lines.
- Verification: Always verify authenticity through XINGLIGHT authorized channels to ensure compliance with the ROHS and MSL specifications.
- Yield Rate: To maintain high yield, strict adherence to the recommended 240°C soldering profile (rather than the absolute 260°C limit) is advised.
- Samples: Engineering samples are recommended for testing spectral response in specific lighting environments.
❓ Frequently Asked Questions
Q: What is the peak wavelength sensitivity for the XL-PD15-22C? A: The photodiode is optimized for a peak sensitivity wavelength (λP) of 940nm, making it ideal for standard infrared remote control and data transmission applications.
Q: What are the soldering requirements for this component? A: The maximum soldering temperature is 260°C for ≤6 seconds. However, XINGLIGHT recommends controlling the peak temperature at 240°C/6s to ensure product longevity and reliability.
Q: What is the Moisture Sensitivity Level (MSL) of this device? A: The XL-PD15-22C is rated at MSL 3. This means it has a floor life of 168 hours after opening the moisture-proof barrier bag before it requires baking prior to reflow soldering.
Q: Can this component be used for outdoor applications? A: The operating temperature range is -20°C to +85°C. While it has a storage range down to -40°C, continuous outdoor operation below -20°C is not recommended without thermal management.
Q: How fast is the response time of this diode? A: Both the rise time (Tr) and fall time (Tf) are typically 10μs under test conditions (VR=10V, RL=1kΩ). This allows for adequate signal bandwidth in remote control and moderate-speed data transmission.
