XL-324SURSYGW is a red–yellowish green bicolor through-hole LED in F3 package (diameter 3.8 mm, height 5.3 mm, lead length 28 mm). It features diffused (light-diffusing) resin and a long-lead design for easy panel mounting or manual soldering, with a non-polar (bipolar) pin configuration that requires no polarity identification.
RoHS compliant and Moisture Sensitivity Level (MSL) 2. It offers low power consumption, long service life and high reliability, with a narrow 30° viewing angle (focused type). The diffused resin effectively softens light and reduces glare, making it suitable for applications requiring bicolor indication with uniform light spot distribution.

Optical Characteristics
Red Chip
Dominant Wavelength (λd): 625~645 nm (typical peak: 635 nm, slightly orange-red compared with conventional red LEDs)
Luminous Intensity (IV): 50~400 mcd (@20 mA, see datasheet for binning details)
Yellowish-Green Chip
Dominant Wavelength (λd): 560~575 nm (typical peak: 570 nm)
Luminous Intensity (IV): 100~500 mcd (@20 mA, see datasheet for binning details)
Viewing Angle (2θ₁/₂): 30°
(Ultra-narrow angle with highly concentrated light output)
Resin Type: Diffused (frosted). Compared with clear resin, diffused resin achieves light diffusion to deliver softer and more uniform light spots, mitigating glare during direct viewing, while maintaining a narrow beam angle.
Electrical Parameters (Ta=25°C)
Red Chip
Maximum Power Dissipation: 50 mW
Maximum Continuous Forward Current: 20 mA
Forward Voltage: 1.8~2.4 V (@20 mA)
Yellowish-Green Chip
Maximum Power Dissipation: 50 mW
Maximum Continuous Forward Current: 20 mA
Forward Voltage: 1.8~2.4 V (@20 mA)
Maximum Pulse Peak Forward Current (IFP): 80 mA (Pulse width ≤0.1 ms, Duty cycle ≤1/10)
Reverse Current (IR): ≤10 μA (VR=5 V)
ESD Withstand Capacity: <1000 V (Human Body Model, HBM); ≤100 V (Machine Model, MM). Lower than SMD LEDs, enhanced ESD protection is required during application.
