Forward Voltage and Wavelength Quick Reference by Color
Voltage varies significantly between colors in the same package. Select current-limiting resistors using the values for the specific color:
| Emission Color | Wavelength Range | Forward Voltage | Chip Material |
|---|---|---|---|
| Red | 620~625nm | 1.8~2.4V | AlGaInP |
| Yellow | 585~595nm | 1.8~2.4V | AlGaInP |
| Orange | 600~610nm | 1.8~2.4V | AlGaInP |
| Standard Green | 565~575nm | 1.8~2.4V | AlGaInP |
| Emerald Green | 520~530nm | 2.8~3.4V | InGaN |
| Blue | 450~470nm | 2.8~3.4V | InGaN |
| White (Neutral White) | Full Spectrum | 3.0~3.4V | InGaN + phosphor |
Q: Can a 5mm round-top LED reach 0.5W?
A: Yes. A large chip and a heat-dissipating lead frame design support a 150mA-class drive current, providing several times the brightness of conventional 20mA round-head LEDs. Heat dissipation and current limiting must be considered; sample validation is recommended before volume use.
