📦 Package, Dimensions & Assembly Notes
The device utilizes a standard 125.214.2mm surface-mount package with EIA standard packaging.
🔒 Moisture Sensitivity: Classified as MSL 2, requiring a floor life of less than one year at <30℃/60% RH. Anti-static foil bags are standard.
Soldering Profile:
- Max Soldering Temp: 260℃
- Time: ≤5 Seconds
⚠️ Note: Ensure proper grounding during assembly; the datasheet mandates an electrostatic field voltage <100V within a 1-foot radius of the component to prevent latent damage.
🚢 Sourcing & Supply Considerations
To ensure supply chain continuity and manufacturing consistency, verify the following points when procuring the XL-DZ234UGD:
- Binning Verification: Confirm brightness (A7-B2) and voltage (N13-2 to N13-5) bin codes to match your PCB power budget and uniformity requirements.
- Packaging Integrity: Validate that seals are intact to ensure the MSL 2 rating has not been compromised by moisture exposure.
- Authenticity: Source through authorized channels to guarantee ROHS compliance and the specified 2000V ESD protection.
❓ FAQ
Q: What is the forward current limit for the entire 4-SMD chip array?
The maximum continuous forward current is 80mA (calculated as 20mA * 4 chips). Designers must ensure the driving current does not exceed this aggregate limit to prevent thermal runaway.
Q: How should the pins be handled to prevent ESD damage during assembly?
All machinery and personnel must be grounded. Use anti-static wrist straps, mats, and ion fans to keep the electrostatic field below 100V within one foot of the device. Standard plastic containers should be avoided.
Q: What are the storage requirements if the components are not used immediately?
Store in the original packaging at temperatures ≤30℃ and relative humidity ≤70%. If storage exceeds three months, use a desiccant cabinet or nitrogen-filled dry box to prevent moisture ingress.
Q: Can this component withstand high-humidity environments?
Yes, the datasheet specifies successful endurance testing at 85℃ and 85-90% RH for 1000 hours, making it suitable for harsh industrial and server environments.
Q: What is the typical viewing angle for this LED?
The viewing angle (2Ø1/2) is typically 110 degrees. This wide angle is suitable for status indicators that need to be visible from off-axe positions.
