The **LXK2-PD12-R00** belongs to the **LUXEON K2** series of high-power LEDs manufactured by Lumileds. While this specific series is now considered "legacy" (discontinued or superseded by the LUXEON TX/Z lines), it was a pioneer in high-brightness LED technology. Below are the detailed electronic and technical specifications for this part. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Manufacturer** | Lumileds | | **Series** | LUXEON K2 | | **Color** | Red (Deep Red/Red) | | **Wavelength (Typical)** | 627 nm | | **Package Type** | Surface Mount (SMD) with slug for thermal management | ### 2. Absolute Maximum Ratings To ensure the longevity of the component, the following limits should not be exceeded: | Parameter | Maximum Rating | | :--- | :--- | | **Forward Current (DC)** | Up to 1000 mA (with adequate heat sinking) | | **Peak Pulsed Current** | 1500 mA | | **LED Junction Temperature** | 135°C | | **Operating Case Temp** | -40°C to 120°C | | **ESD Sensitivity** | > 8,000V (HBM) | ### 3. Electrical Characteristics These values are typical at a test current of **350 mA** and a junction temperature of **25°C**: * **Forward Voltage ($V_f$):** * Minimum: 2.03 V * Typical: 2.30 V * Maximum: 3.03 V * **Thermal Resistance ($R_{thj-c}$):** Approximately 9°C/W (low thermal resistance allows for high drive currents). ### 4. Optical Performance | Metric | Value | | :--- | :--- | | **Luminous Flux (Typical)** | ~45 Lumens @ 350mA | | **Viewing Angle** | 140 degrees (Lambertian radiation pattern) | | **Radiometric Power** | High output suitable for signaling and illumination | --- ### 5. Design Considerations * **Thermal Management:** The LXK2-PD12-R00 features a large "slug" on the bottom. This is **not** electrically neutral in some K2 models (check the specific datasheet footprint); it must be soldered to a metal-core PCB (MCPCB) to dissipate heat. * **Drive Circuitry:** A constant current driver is required. Using a constant voltage source will lead to thermal runaway and component failure. * **Lens Compatibility:** The dome is made of silicone, which is durable but sensitive to mechanical pressure. ---
