📌 Product Overview
The XL-A524SURSYGC is a discrete 5mm bicolor LED component manufactured by XINGLIGHT. It integrates high-brightness Red and Yellow-Green chips into a single, water-clear, T-1 3/4 (5mm) package with a common cathode polarity.
👇 This component is specifically engineered for applications requiring dual-status indication or mixed-color output in a compact through-hole form factor. It is designed to support straightforward PCB integration while maintaining visibility in varied lighting environments.
🚀 Typical Applications
Based on the 30-degree viewing angle and dual-color configuration, the XL-A524SURSYGC is suited for the following specific scenarios:
- Automotive Interior Indication: Dashboard status lights and control panel feedback.
- Backlight Modules: Indicator illumination for switches and buttons.
- Signal Indication: Power status, operational mode, or error warnings in consumer appliances.
- Smart Home Devices: Status LEDs for hubs, sensors, and IoT actuators.

🚨 Absolute Maximum Ratings & Process Limits
Exceeding these parameters may result in permanent device failure. Design margins must account for these absolute limits to ensure reliability in automotive and industrial environments.
| Parameter | Symbol | Red | Yellow Green (YG) | Unit |
|---|---|---|---|---|
| Max Power Dissipation | $P_D$ | 50 | 70 | mW |
| Max Continuous Forward Current | $I_F$ | 20 | 20 | mA |
| Peak Forward Current | $I_{FP}$ | 80 | 80 | mA |
| Operating Temperature | $T_{OPR}$ | -20 to +85 | -20 to +85 | $^\circ\text{C}$ |
| Storage Temperature | $T_{STR}$ | -40 to +85 | -40 to +85 | $^\circ\text{C}$ |
⚠️ Soldering limits are strictly defined: Wave soldering max $240^\circ\text{C}$ for $\le 6\text{s}$; Manual welding max $300^\circ\text{C}$ for $\le 3\text{s}$. Keep soldering point $>2.0\text{mm}$ from the colloid base.
📦 Package, Dimensions & Assembly Notes
The component utilizes the standard F5 radial package, also known as T-1 3/4.
- Dimensions: The overall body length is specified at $28\text{mm}$, with a standard bulb diameter suitable for 5mm LED clips.
- Lens Material: The water-clear (transparent) colloid maximizes light output but requires consideration of ambient washout in high-brightness environments.
- MSL Level: The component is classified at Moisture Sensitivity Level 2 (MSL 2).
- Assembly: Standard EIA packaging allows for automated radial lead cutting and forming equipment.
🔒 Sourcing & Supply Considerations
To mitigate supply chain risks, procurement teams should verify the specific binning codes (brightness and voltage) when placing orders to match previous production lots.
- Compliance: The product meets ROHS requirements, essential for EU and general export markets.
- Authenticity: Source from authorized channels to ensure compliance with the stated lifespan and reliability test parameters.
- Volume Planning: Consider EIA standard packaging for automated feeder setup in high-volume assembly lines.
❓ FAQ
Q: What is the forward voltage requirement for the Green chip?
A: The Yellow-Green chip typically has a forward voltage ($V_F$) range of 1.8V to 2.6V at 20mA. Designers should use the upper limit (2.6V) for resistor sizing to ensure consistent brightness across the voltage tolerance.
Q: Is this component suitable for wave soldering processes?
A: Yes, the XL-A524SURSYGC is rated for wave soldering. However, the temperature must not exceed $240^\circ\text{C}$ and exposure time must be limited to 6 seconds maximum to prevent damage to the internal die bond.
Q: What is the moisture sensitivity level (MSL) for this LED?
A: The datasheet specifies an MSL of 2. This means the components can be exposed to ambient air (up to $30^\circ\text{C}$ / 85% RH) for up to one year before baking is required prior to soldering.
Q: How is the color consistency controlled in production batches?
A: XINGLIGHT utilizes specific wavelength grading codes (e.g., HR02 for Red, HYG04 for Green). When sourcing, specifying these bin codes ensures that the color coordinates remain consistent across different production lots.
Q: What is the peak forward current allowed?
A: The Absolute Maximum Rating for peak forward current ($I_{FP}$) is 80mA. This is intended for pulsed operation only; driving the LED continuously at this current will likely cause thermal failure.
