📦 Package, Dimensions & Assembly Notes
- Package Type: F5 Round (Metal Base Lamp Seat)
- Dimensions: $11.3 \times 15.0 \times 10.3\text{ mm}$ (Appearance Dimension).
- Moisture Sensitivity: MSL Level 2 (Must be baked/used within 1 year if sealed, or per manufacturer's floor life instructions).
- Packaging: EIA Standard Packaging, shipped in moisture-proof and anti-electrostatic foil bags.
🔒 Assembly Note: When soldering manually, ensure the soldering point is at least 2.0mm away from the bottom of the colloid to prevent thermal damage to the epoxy lens and internal bonding wires.
🚢 Sourcing & Supply Considerations
- Binning Codes: Verify specific brightness (Code A8-B4) and voltage (Code N13-3 to N13-6) binning requirements with the supplier to match circuit design limits.
- Authenticity: Source through XINGLIGHT authorized channels to guarantee RoHS compliance and MSL 2 integrity.
- Yield Management: For high-volume orders involving strict wavelength control (HB04-HB06), coordinate with the distributor to secure consistent manufacturing lots.
❓ Frequently Asked Questions
Q: What is the forward voltage range required to drive this LED at 20mA?
A: The forward voltage ($V_F$) varies between 2.8V and 3.6V depending on the specific bin. Designers should account for this range to ensure constant current regulation and avoid over-driving the lower voltage bins.
Q: Is the XL-DZT502UBD1 compatible with lead-free soldering processes?
A: Yes, the datasheet specifies compliance with ROHS requirements. For wave soldering, the maximum temperature is $240^\circ C$ for $\le 6\text{ seconds}$. Manual soldering should not exceed $300^\circ C$ for 3 seconds.
Q: How should I handle storage to prevent moisture damage?
A: This LED has a Moisture Sensitivity Level (MSL) of 2. If the moisture-proof barrier bag is opened, components should be used within the specified floor life (typically 1 year for MSL 2) or baked according to IPC/JEDEC standards before reflow soldering.
Q: What does the brightness binning code (e.g., A8, B1) signify?
A: The brightness codes (A8 through B4) indicate the luminous intensity in millicandelas (mcd). For instance, Code A8 ranges from 900–1200 mcd, while Code B4 ranges from 2500–3000 mcd. Selecting a specific bin helps maintain visual uniformity across your product line.
Q: What safety margin should I leave for the peak current?
A: While the Absolute Maximum Rating for peak forward current ($I_{Fp}$) is 80mA, this is a pulsed value. For continuous operation, strictly limit the current to 20mA. Pulses above 20mA must be short-duration and low-duty-cycle to prevent thermal runaway.
