Key Features
- Dual-color Super Red (630 nm, 55 mcd) and Bright Green (570 nm, 30 mcd) elements in a single 1210 SMT package for 2-color status display
- Separate independent anodes per color allow individual or simultaneous drive to produce red, green, or mixed amber indication
- Water-clear (colorless) lens maximizes color fidelity and allows precise wavelength differentiation at the optical level
- Ultra-low 0.7 mm profile suits thin product designs such as wearables, smart cards, and ultra-slim PCB assemblies
- 130° viewing angle provides wide angular coverage for front-panel indicators visible to operators across a workspace
- Maximum forward current of 30 mA per element with 2.0 V forward voltage for straightforward GPIO drive design
Applications
The Würth Elektronik 150121SV74000 is designed for PCB status indicators that must convey two distinct states—power-on (green) and fault or alert (red)—using a single compact 1210 SMT footprint. It is widely used in IoT sensor nodes, handheld test instruments, and industrial relay modules where board space is limited and two-color feedback replaces two separate LED positions. The 130° viewing angle and water-clear lens ensure the color distinction is clearly visible from a wide range of operator viewing angles without additional optics.

Frequently Asked Questions
How can both Super Red and Bright Green elements of the 150121SV74000 be driven simultaneously to produce a mixed amber color?
Because the 150121SV74000 has separate, independent anode pins for each color, both elements can be turned on at the same time. Driving the Super Red at 20 mA and the Bright Green at 10 mA produces a mixed amber/yellow appearance (approximately 595 nm weighted average) visible through the water-clear lens, giving a 3-state indicator—red, green, amber—from a single 1210 package and two PWM-capable GPIO pins.
What current-limiting resistors are needed to drive each color element at 20 mA from a 3.3 V MCU supply rail?
Both elements have a forward voltage of 2.0 V typical. At 20 mA from a 3.3 V supply, each series resistor should be (3.3 V − 2.0 V) / 0.020 A = 65 Ω. The nearest standard E24 value is 68 Ω, setting current to 19.1 mA — safely below the 30 mA maximum. One 68 Ω resistor per color element is sufficient for direct GPIO-sourced drive at 3.3 V logic levels.
How does the 1210 package size and 0.7 mm height of the 150121SV74000 compare to alternative bi-color LED packages?
The 1210 (3.2 mm × 2.5 mm) footprint of the 150121SV74000 at 0.7 mm height is larger than 0603 bi-color LEDs but provides higher luminous intensity (55/30 mcd) and more robust pad adhesion. Competing 1206 bi-color LEDs offer a similar footprint but typically reach only 20–40 mcd at 20 mA, making the 150121SV74000 preferable for applications needing visibility from more than 1 m.
What is the dominant wavelength for each element and how does this affect color accuracy in status indicator designs?
The Super Red element emits at 630 nm dominant wavelength and the Bright Green element at 570 nm. These values sit near the center of the human eye's photopic sensitivity curve for green and at the deep-red boundary, ensuring strong perceptual contrast between the two colors. Designers should note that viewing through colored panels or diffusers may shift apparent hue by 5–15 nm, so a water-clear or near-clear panel is recommended for accurate color rendering.
