Overview
The Dialight 553-0711-400F is a bi-level, right-angle LED circuit board indicator designed for space-constrained panel applications. Its primary function is to provide distinct visual status feedback using two independent LEDs, a green and a red, within a single T-1 (3mm) package. A critical design consideration for this component is managing the forward voltage differential between the green (2.1V) and red (2V) emitters to ensure consistent brightness and accurate state indication, especially when driven by a common current source, a trade-off that necessitates careful resistor selection to avoid premature red LED saturation or insufficient green illumination.
Key Features
