👇 Process Alert: The MSL (Moisture Sensitivity Level) is 2. Boards must be baked within 1 year of exposure if sealed bags are opened, prior to reflow to prevent popcorning.
📦 Package, Dimensions & Assembly Notes
The component uses a standard 12mm bulb package with a 2.54mm lead pitch, suitable for wave soldering or manual insertion.
- Dimensions: 12.0 (L) x 5.2 (W) x 14.2 (H) mm.
- Tolerance: ±0.25mm for unmarked dimensions.
- Packaging: ESD-safe, moisture-proof foil bags (EIA standard).
- Assembly: 🔒 Lead soldering max is 260°C for 5 seconds. Avoid excessive mechanical stress on the lead frame (bending load limit 0.25kgf).
🚀 Sourcing & Supply Considerations
- Binning Selection: The datasheet specifies distinct binning codes for Brightness (A1-A3), Voltage (N12), and Wavelength (HYG01-06). 💡 Request specific bins (e.g., A3 for brightness) to ensure visual uniformity on the production line.
- Authenticity: Verify anti-static bag sealing integrity upon receipt.
- Lead Time: 12mm THT LEDs generally offer better availability than SMD alternatives, but green-yellow specific bins may have longer lead times.
❓ FAQ
Q: What is the difference between this 4-chip LED and standard single-chip indicators?
A: The XL-DZ234SYGD integrates four dies into one lens, significantly increasing luminous intensity (up to 300mcd) and total power dissipation (200mW) compared to standard single-chip LEDs. This makes it suitable for environments requiring high visibility or longer viewing distances.
Q: Can I drive this LED with a standard 5V microcontroller GPIO?
A: Generally, no. While the max reverse voltage is 5V, the forward voltage is 1.8-2.4V. Connecting directly to 5V without a current-limiting resistor will likely destroy the LED due to excessive current. A series resistor is mandatory.
Q: How should I manage the storage of this component prior to assembly?
A: Store at <30°C and <70% RH. The MSL is 2, meaning it can sit on the factory floor for up to 1 year (after bag opening) before baking is required. For long-term storage, keep in the original moisture-proof bag with desiccant.
Q: What is the importance of the wavelength binning (HYG codes)?
A: The codes HYG01 to HYG06 split the 560-575nm range into smaller increments. 💡 If you are designing an array of status lights (e.g., server racks), ordering the same bin code ensures that every LED appears visually identical in color, preventing a "patchy" look.
Q: What are the mechanical limits for the leads during assembly?
A: The leads can withstand a load of 2.5N (0.25kgf) during bending. Support the lead body during forming to avoid stress on the epoxy body, which can cause cracking or hermeticity failure.
