5977721507F

LED Indication - Discrete Overview

Dialight 5977721507F is a bi-color surface-mount LED emitting green and yellow light. It features a clear lens with a rectangular shape and flat top, housed in a 4-SMD no-lead package measuring 3.00mm x 2.50mm x 1.30mm. The component operates at a forward current of 20mA for both colors, with typical forward voltages of 2.2V (green) and 2.1V (yellow). Peak wavelengths are 570nm (green) and 585nm (yellow), while dominant wavelengths are 575nm and 589nm respectively. Luminous intensity is 21mcd for green and 10mcd for yellow. It has a viewing angle of 100 degrees and an operating temperature range of -55°C to +100°C.

LED Indication - Discrete Feature Summary

• Bi-color configuration providing independent green and yellow emission within a single compact SMD footprint.
• Clear non-diffused lens design optimized for direct visibility applications requiring distinct color indication.
• Industrial-grade thermal stability supporting operation across extreme ambient temperatures from -55°C to +100°C.

LED Indication - Discrete Applications

• Panel-mounted status indicators for industrial control equipment
• Signal lights for electronic test and measurement instruments
• Multi-state visual feedback systems in automotive electronics

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct lens type and wavelength specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements during storage and handling. Cross-reference the package dimensions with PCB layout constraints to ensure accurate placement. Check for any recent product change notices regarding manufacturing site transfers or material updates.

LED Indication - Discrete Selection Notes

Select this component when a dual-color indication is required in a limited space without increasing board area. The 100-degree viewing angle offers moderate directional visibility suitable for panel mounting. Consider the forward voltage differences between green and yellow channels when designing drive circuits. Ensure the 20mA test current aligns with available driver capabilities and power budget constraints.
