Key Features
- Bi-color red and green LED in a single 3 mm T-1 through-hole package, enabling dual-color status indication with minimal PCB footprint
- Common-cathode or common-anode configuration allows simple GPIO-driven color selection using logic-level signals from 3.3 V or 5 V MCU outputs
- Standard 3 mm (T-1) body fits universal LED mounting holes and light pipes, simplifying panel indicator and front-panel display integration
- Separately driven red and green dies allow amber/yellow appearance by simultaneous activation, providing 3 distinct status colors from 2 control lines
Applications
W115WSURKMGKW is used as a dual-color status indicator on industrial control panels, network switches, and consumer electronics front panels where red and green colors indicate operating states such as fault versus normal, or transmit versus receive. The single 3 mm through-hole package simplifies panel drilling and reduces BOM count compared to two separate single-color LEDs. It is also common in power supply status indicators, battery charge monitors, and embedded development board debugging LEDs driven directly by GPIO pins.

Frequently Asked Questions
What forward current and forward voltage are typical for each color in W115WSURKMGKW at standard operating conditions?
For a standard 3 mm bi-color LED like W115WSURKMGKW, the red emitter typically operates at 20 mA forward current with a 2.0 V to 2.2 V forward voltage, while the green emitter operates at 20 mA with approximately 2.1 V to 2.4 V forward voltage. A series resistor of 150 Ω on a 5 V supply limits current to approximately 20 mA per channel, ensuring rated brightness and long LED lifetime.
Can W115WSURKMGKW produce a yellow or amber color by driving both red and green simultaneously?
Yes. When both the red and green emitters in W115WSURKMGKW are forward biased simultaneously at approximately 20 mA each, the human eye perceives the combined emission as amber or yellow. This allows 3 distinct status colors from just 2 GPIO control lines: red only, green only, and amber/yellow when both are active, covering fault, normal, and standby states on a single 3 mm indicator.
How does using W115WSURKMGKW instead of two separate single-color LEDs reduce PCB cost and assembly time?
W115WSURKMGKW combines red and green emitters in one 3 mm T-1 body requiring only a single 3 mm panel hole and one PCB footprint, compared to 2 drilled holes, 2 separate LED packages, and 2 individual soldering operations for discrete alternatives. In a production run of 10,000 units, this saves approximately 10,000 drilling operations and reduces LED placement cycle time by 50%, lowering per-unit assembly cost by several cents.
