LED1642GW

LED1642GW is a high-brightness, surface-mount LED from STMicroelectronics designed for efficient illumination in a wide range of applications. It features a 1642 package size (16 mm x 4.2 mm), offering a compact form factor suitable for space-constrained designs while maintaining excellent thermal performance. The device emits light in the green spectrum, typically with a peak wavelength around 520–530 nm, ensuring vibrant visibility under various lighting conditions. This LED operates at a forward current of up to 350 mA and supports a maximum continuous forward current of 700 mA, enabling high luminous output without compromising reliability. Its typical forward voltage ranges from 2.8 V to 3.4 V, making it compatible with standard driver circuits and power supplies. The LED is built using advanced GaN-on-Si technology, which enhances efficiency, reduces heat generation, and increases overall lifespan—often exceeding 50,000 hours under normal operating conditions. Key characteristics include a wide viewing angle of approximately 120°, ensuring uniform light distribution across a broad area, and a high lumen output that makes it ideal for indicator and backlighting tasks. The epoxy lens provides robust mechanical protection and maintains optical consistency over time, even in harsh environments. Additionally, the LED is RoHS-compliant and halogen-free, aligning with environmental standards for modern electronics manufacturing. Applications for the LED1642GW span industrial control panels, automotive lighting systems, consumer electronics such as displays and keyboards, and medical equipment requiring precise visual feedback. Its reliable performance in both static and dynamic lighting scenarios makes it suitable for use in traffic signals, signage, and portable devices where consistent brightness and long-term stability are critical. The device also offers excellent thermal management due to its low thermal resistance, allowing efficient heat dissipation through the PCB when properly mounted. This ensures stable operation even under prolonged use or elevated ambient temperatures. With its durable construction and optimized electrical characteristics, the LED1642GW delivers dependable performance across diverse operational environments—from indoor consumer products to outdoor industrial installations.
