ð Product Overview
The XL-3433SURC-05 is a high-performance Red SMD LED manufactured by XINGLIGHT. ðĄ Housed in a compact 3.4x3.3mm package with a colorless transparent lens, it is engineered to deliver intense luminosity suitable for challenging environments.
Target applications primarily include automotive lighting (such as taillights and interior illumination) and commercial signage. ð The real design focus lies in its ability to handle a maximum continuous forward current of 150mA. This makes it ideal for designers needing high-reliability components for SMT automated production and infrared reflow soldering processes.
ð Typical Applications
Based on the datasheet parameters, particularly the high luminous intensity and wide viewing angle, this component fits the following use cases:
- Automotive Lighting: Tail lights, turn signals, and interior cabin lights.
- Commercial Display: Advertising lightboxes and channel letters.
- Backlighting: LCD backlight units requiring uniform red illumination.
- Decorative Lighting: Flexible light strips for accent or mood lighting.

â FAQ
Q: What is the maximum current I can drive the XL-3433SURC-05 with continuously?
A: The Absolute Maximum Rating for continuous forward current is 150mA. While it can handle peaks up to 300mA, continuous operation above 150mA will degrade the lifespan.
Q: Is this LED suitable for outdoor automotive use?
A: Yes, it is designed for automotive applications. However, the -40â to +85â operating range must be respected, and adequate moisture protection (MSL 3) should be considered during the PCB assembly process.
Q: What does the "Colorless Transparent" colloid mean for my design?
A: It means the encapsulation resin is clear. This typically results in higher luminous intensity and a wider viewing angle (120°) compared to diffused lenses, but it requires careful optical design to avoid hotspots.
Q: Can I use a standard leaded soldering profile?
A: The datasheet specifies parameters for both Lead and Lead-Free processes. For lead-free, do not exceed a peak temperature of 260â (255â recommended).
Q: How do I ensure color consistency across batches?
A: Use the Dominant Wavelength binning codes (HR01, HR02, HR03). Requesting a specific bin code when ordering ensures the red hue remains consistent across your product line.
Q: What is the Moisture Sensitivity Level (MSL)?
A: It is Level 3. This means the components can be exposed to ambient climate for 168 hours (one week) before they require baking prior to soldering to prevent internal damage.
