📦 Package, Dimensions & Assembly Notes
Physical Characteristics: The device features a compact molded package with Outline Dimensions of 6.4mm (L) x 3.9mm (W) x 1.2mm (H). 👇 The standard EIA compliant packaging ensures compatibility with automated pick-and-place machinery.
Soldering Guidelines: To prevent mechanical stress or thermal shock:
- Reflow Soldering: Recommended max temperature is 240°C for ≤10 seconds. It is advised to perform only one reflow cycle to maintain terminal integrity.
- Manual Soldering: Iron tip temperature must remain below 300°C for under 3 seconds per terminal. Do not apply mechanical pressure to the resin body while heating.
- MSL Handling: As a Level 3 moisture-sensitive device, ensure proper baking if the floor life (168 hours) is exceeded before reflow.
🚀 Sourcing & Supply Considerations
When integrating the XL-PD70-01B-TR into production BOMs, consider the following supply chain factors to ensure continuity and quality:
- Authenticity Verification: Cross-reference packaging labels (EIA standard box/foil bag) to confirm origin and prevent counterfeit integration.
- BOM Optimization: Evaluate the component's consistency in "Light Current vs. Illuminance" to minimize calibration efforts in mass production.
- Lead-Time Management: This model utilizes standard EIA packaging, which generally offers better logistics stability compared to proprietary custom trays.
❓ FAQ
Q: What is the peak detection wavelength for this photodiode?A: The XL-PD70-01B-TR has a peak spectral sensitivity (λp) at 940nm, making it optimized for standard infrared communication protocols and specific industrial laser/LED sources.
Q: Can this component withstand lead-free soldering processes?A: Yes, the datasheet specifies a maximum welding temperature of 260°C (≤6S), accommodating standard lead-free profiles. However, XINGLIGHT recommends keeping the peak closer to 240°C (≤10S) to maximize component lifespan.
Q: What does Moisture Sensitivity Level (MSL) 3 mean for storage?A: MSL 3 indicates the components can be exposed to factory ambient conditions (≤30°C / 60% RH) for 168 hours (1 week) after opening the vacuum seal before they must be soldered to avoid internal "popcorning" damage.
Q: How is the reverse light current (IL) tested?A: The representative IL of 20μA is measured with a Reverse Voltage (VR) of 5V and an irradiance (Ee) of 1mW/cm² at the peak wavelength of 940nm.
Q: Is manual repair/rework of this LED allowed?A: Repairing after soldering is generally not recommended. If unavoidable, use a double-head soldering iron to heat both terminals simultaneously and minimize thermal stress on the epoxy body. Verify characteristics post-rework.
