📦 Package, Dimensions & Assembly Notes
The XL-DZ304SYGD utilizes a standard 7.5 x 6.5 x 4.5 mm molded package with radial leads, designed for easy insertion and wave soldering.
- Dimensions: The bulb diameter and lead spacing conform to standard 3mm indicator footprints (Tolerances: $\pm 0.25\text{mm}$).
- Packaging: Supplied in EIA standard compliant bags, utilizing moisture-proof and anti-static foil bags to preserve component integrity.
- Assembly: Supports standard lead soldering profiles up to 260℃. Ensure PCB layout accounts for the 4.5mm height.
- Colloid: The green epoxy package matches the yellow-green emission, providing a uniform off-state appearance.
🚀 Sourcing & Supply Considerations
When integrating the XL-DZ304SYGD into BOMs, consider these supply chain factors:
- Binning Management: The datasheet specifies distinct bins for Brightness (A1/A2) and Voltage (N12-7 to N13-1). For high-uniformity panels, strict bin selection is recommended.
- Compliance: Verified RoHS compliant, ensuring suitability for international markets and environmentally sensitive designs.
- Packaging: Bagged packaging format is ideal for lower-volume manual assembly or reeling for automated pick-and-place if requested.
❓ FAQ
Q: What are the available color and binning options for this model?
A: The XL-DZ304SYGD features a Yellow-Green luminous color ($560\text{--}575\text{nm}$) with a Green colloid body. It is available in Brightness bins A1 (50–100 mcd) and A2 (100–200 mcd), as well as Voltage bins from 1.8V to 2.6V.
Q: Is this LED suitable for automated SMT assembly lines?
A: While the primary packaging is in bags (suitable for manual or semi-auto use), the 3mm radial lead design is inherently a Through-Hole Technology (THT) component. It is designed for wave soldering or manual insertion rather than standard high-speed SMT pick-and-place.
Q: What is the moisture sensitivity requirement before soldering?
A: The component is classified as MSL 2. It must be mounted within 1 year of the packaging date, or if the moisture barrier bag has been opened, floor life should be managed according to J-STD-033 standards (typically 1 year from seal if dry).
Q: How does the forward voltage impact driver design?
A: With a maximum forward voltage of 2.6V at 20mA, the LED can be driven directly by standard 3.3V logic with a small current-limiting resistor, or efficiently driven by 5V supply rails. Calculations should use the 2.6V max value to ensure consistent current across all voltage bins.
