会社のニュース LED Application Scenarios: Anti Static Bi Color PLCC4 3528 SMD LED Red & Blue 60mW for Indicators & Signage

From automotive electronics and appliance panels to vivid signage and industrial control boards, modern LED application scenarios reward components that combine two-color versatility with rugged electrostatic protection. This article explores how one compact part can serve them all, and it puts the spotlight on a single model: the Anti Static Bi Color PLCC4 3528 SMD LED (Red & Blue, 4 pins, 60mW).

Why Bi-Color SMD LEDs Are Everywhere

A bi-color SMD LED places two emitters inside one tiny package, so a single component can signal two states—red for warning, blue for active, and so on—without doubling board area. That “two-in-one” advantage is exactly why an anti static smd led bicolor has become a default choice for indicators, backlit keypads and compact displays.

• Two colors, one footprint for smarter panel design
• Low current operation at just 20 mA
• Good heat dissipation and low light attenuation
• Strong anti-static ability for high-yield SMT
• RoHS compliant and easy to install

Hero Model: Bi Color PLCC4 3528 SMD LED (Red & Blue)

Built on the PLCC4 3528 package, 3.5 × 2.8 × 1.9 mm, this four-pin device pairs a red die at 620–635 nm with a blue die at 460–470 nm. The molded body emits from the positive side (top-emitting), delivering a crisp, uniform glow at a 120° viewing angle. Because it uses advanced AlGaInP / InGaN chip technology and a robust anti-static structure, this anti static smd diode led stays stable through the electrostatic discharge typical of fast reflow lines.

Technical Parameters

Where It Shines: Application Scenarios

1. Optical indicators — status lights that switch between two clear colors.
2. Automotive electronics — interior lighting, dash and signal tell-tales.
3. Backlighting — LCD panels, switches and symbol displays.
4. Light pipe & signage — advertisement and point-of-sale displays.
5. Traffic & safety products — traffic lights and warning indicators.
6. Decorative modules — LED modules, strips and accent lighting.

A True 60mW SMD LED on the Positive Side

Because the die sits on the positive side (top-emitting surface) of the package, the light exits cleanly toward the lens or light pipe, with minimal side leakage. At just 0.06 W (60 mW) of power and a 20 mA drive, this 60mw smd led positive side component keeps heat and energy consumption low—ideal for dense indicator arrays and battery-sensitive portable electronics where efficiency matters as much as brightness.

Anti-Static Reliability Built In

Brightness consistency means little without reliability. Engineered as a genuine anti static smd led bicolor, this part resists the electrostatic discharge that plagues rapid placement and reflow, protecting both yield and long-term output. The result is fewer rejects, stable color and a smoother mass-production line—exactly what high-volume projects require.
