Product type
Bi-color LEDs are light-emitting diodes that can emit light in two different colors, typically red and green, using a single package. They are constructed with two different semiconductor materials, allowing them to produce two distinct colors depending on the polarity of the voltage applied. This dual functionality makes them versatile for various signaling and indicator applications.
| Forward Voltage | 1.8V to 3.6V |
| Wavelength | 620nm (Red) and 525nm (Green) |
| Package Type | Through-hole or SMD |
| Operating Temperature | -40°C to +85°C |
| Luminous Intensity | 100 to 200 mcd |
When selecting bi-color LEDs, consider the forward voltage and current ratings to ensure compatibility with your circuit. Specify the desired colors and any specific packaging requirements, such as through-hole or surface mount. It's also important to check for luminous intensity and operating temperature ranges based on your application needs. Quantities can vary widely, so be clear about your order volume when requesting a quote.

Typically, they emit red and green, but other color combinations are available.
Connect the anode to the positive voltage and the cathode to ground for one color, and reverse the connections for the other color.
Bi-color LEDs generally have a lifespan of 25,000 to 50,000 hours.
Yes, they can be dimmed by adjusting the current supplied to them.
It depends on the specific model; check for IP ratings for outdoor applications.
They are available in various sizes, with common package sizes being 3mm and 5mm.
