156125RV73000

Overview

The Würth Elektronik 156125RV73000 is a dual-color surface-mount LED featuring green and red emitters in a 4-SMD bottom-entry package. It operates with a typical forward voltage of 2.1V for the green channel and 2V for the red channel, tested at 20mA each. The device emits light at peak wavelengths of 573nm (green) and 632nm (red), with main wavelengths of 571nm and 624nm respectively. Luminous intensity reaches 170mcd for green and 110mcd for red, providing a 120-degree viewing angle within a compact 3.20mm x 1.20mm footprint.

Feature Summary

• Dual-color configuration integrating distinct green and red emission sources within a single component
• Bottom-entry SMD mounting style designed for efficient surface placement on printed circuit boards
• Wide 120-degree viewing angle ensuring broad visibility across various installation orientations

Applications

• Status indication for electronic equipment requiring simultaneous multi-state signaling
• Battery pack monitoring systems utilizing integrated optoelectronic components
• Consumer electronics displays needing compact bi-color visual feedback mechanisms

Procurement Notes

Verify the specific ordering suffix to confirm the exact color combination and lens transparency specifications. Ensure compatibility with standard reflow soldering profiles suitable for small surface-mount devices. Confirm that the 4-SMD bottom-entry package dimensions align with the designated PCB land pattern. Check RoHS compliance documentation for adherence to current environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a dual-color indicator within a minimal footprint. The bottom-entry design facilitates automated assembly processes compared to top-view alternatives. Consider the specific luminous intensity requirements for both colors to ensure adequate visibility under intended operating conditions. Verify that the forward voltage characteristics match the available drive circuitry capabilities for reliable operation.

Part Context

This part belongs to the WL-SBRW series, representing Würth Elektronik's portfolio of specialized surface-mount LEDs. The series focuses on providing versatile optical solutions for modern electronic applications where size and performance are critical. As a discrete dual-color device, it offers a cost-effective alternative to separate single-color components while maintaining high reliability standards.

Replacement Considerations

Direct substitutes include other Würth Elektronik dual-color SMD LEDs from the WL-SBRW family with matching pin configurations. Cross-reference mechanical dimensions and thermal characteristics to ensure board compatibility. Verify equivalent electrical parameters such as forward voltage and luminous intensity before implementing any alternative component in existing designs.
