AA3021SESK

Overview

The Kingbright AA3021SESK is a single-color orange light-emitting diode designed for surface-mount technology applications. It operates with a forward current of 20 mA and a forward voltage of 2.1 V, dissipating up to 75 mW of power. The component emits light at a peak wavelength of 601 nm with an optical intensity of 400 mcd. It features a water-clear oval lens measuring 2.5 mm by 1.5 mm with a height of 1.3 mm. The device supports a viewing angle of 125 degrees and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes a compact 1208 (3020 metric) surface-mount package for efficient PCB space utilization.
• Features a water-clear oval lens to maximize light transmission and visibility.
• Provides high-intensity orange emission suitable for indicator applications.

Applications

• Status indicators on electronic control panels
• Power supply status signaling
• General-purpose equipment front-panel illumination

Procurement Notes

Verify the specific suffix 'SESK' against the manufacturer's latest datasheet to confirm packaging format and binning specifications. Ensure compatibility with RoHS directives if required by your assembly process. Cross-reference the Mouser number 604-AA3021SESK for accurate distributor identification and current availability status before finalizing procurement orders.

Selection Notes

Select this component when a low-profile orange LED is required for surface-mount assembly. The 2.1 V forward voltage makes it compatible with standard logic-level driving circuits. Consider the 125-degree viewing angle for wide-area visibility requirements. Verify thermal management capabilities as the maximum operating temperature reaches +85°C.

Part Context

This part belongs to the Kingbright KA-3021 series of single-color LEDs. The series offers various color options in a standardized 3020 SMD footprint. The AA3021SESK specifically denotes the orange variant with water-clear lens characteristics. This series is widely used in consumer electronics and industrial instrumentation for visual signaling.

Replacement Considerations

Direct substitutes include other Kingbright 3020 series orange LEDs such as KA-3021SESK. Verify electrical parameters like forward voltage and luminous intensity when considering cross-brand alternatives from manufacturers offering identical 1208 package dimensions.
