C503T-GAS-CA0E0791

Overview

The C503T-GAS-CA0E0791 is a green light-emitting diode from the Cree LED series, housed in a 5 mm (T-1 3/4) radial through-hole package. It features a colorless lens with a circular shape and transparent surface. The component operates at a maximum forward current of 30mA and has a maximum power dissipation of 120mW. Key electrical parameters include a forward voltage of 3.4V and a test current of 20mA. The device emits light at a dominant wavelength of 527nm with a luminous intensity of 23000 mcd. It supports an operating temperature range from -40°C to +95°C.

Feature Summary

• Provides high luminous intensity for excellent readability in sunlight
• Features a compact 3.4V design suitable for precise voltage indication
• Utilizes a standard radial lead configuration for easy mounting

Applications

• Precise voltage indication circuits
• General purpose status indication
• High-brightness visual signaling

Procurement Notes

Verify the specific suffix CA0E0791 against official Cree documentation to confirm the exact luminous intensity binning and wavelength tolerance. Ensure that the 3.4V forward voltage specification aligns with your circuit design requirements rather than assuming generic green LED characteristics. Confirm RoHS compliance status directly from the manufacturer's latest datasheet or certification documents before finalizing procurement orders.

Selection Notes

Select this component when high brightness is required for visibility in ambient light conditions. The 5mm through-hole format is appropriate for prototyping and applications where surface mount space is limited. Consider the 3.4V forward voltage drop when designing current-limiting resistor networks to ensure proper biasing within the 30mA maximum rating.

Part Context

This part belongs to the Cree LED C503T series, which includes various blue and green variants. The C503T designation typically indicates a specific lens style and lead form factor within the company's portfolio. This model represents a high-performance option within the standard 5mm LED category, distinguished by its superior light output capabilities compared to standard intensity devices.

Replacement Considerations

Direct substitutes must match the 5mm T-1 3/4 package, 527nm wavelength, and high-intensity output. Verify pin compatibility and thermal resistance ratings. Generic green LEDs may not provide the same luminous intensity or forward voltage characteristics.
