5SGD

Overview

The Bivar Inc. 5SGD is a single-color green LED indicator designed for through-hole mounting in a T-1 3/4 (5 mm) package. It emits pure green light at a wavelength of 555 nm with a viewing angle of 45 degrees. The component features a diffused lens and operates within a temperature range of -25°C to +85°C. Key electrical parameters include a forward voltage of 2.1 V, a forward current of 20 mA, and an optical intensity of 10 mcd.

Feature Summary

• Through-hole radial lead configuration for standard PCB assembly
• Diffused lens design providing a 45-degree viewing angle
• Pure green emission optimized for visual status indication

Applications

• Electronic device power status indicators
• Control panel signal lights
• Equipment operational state verification

Procurement Notes

Verify the specific suffix requirements for flanged or non-flanged variants, as the base part number may denote different mechanical configurations. Confirm availability status directly with authorized distributors, as this component has been marked as End of Life in some channels. Ensure that the selected variant matches the required mounting style and lens transparency for the target application.

Selection Notes

Select the 5SGD when a standard 5mm through-hole green LED with a diffused finish is required. Consider the 5SGD-F variant if a flanged mounting option is necessary for the enclosure design. Evaluate the 2.1 V forward voltage drop against the available drive circuitry to ensure proper current limiting resistor calculation. Verify that the 10 mcd intensity meets the visibility requirements for the intended environment.

Part Context

The 5SGD belongs to Bivar's discrete LED indication series, which provides various single-color options for board-level signaling. This specific model represents the standard green emission variant within the 5mm T-1 3/4 form factor. It is distinct from surface-mount alternatives like the SMTLA series and other color variants such as the blue 5BWT-F or red models.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is listed as End of Life, engineers should consult official replacement guides or contact the manufacturer for direct cross-reference recommendations.
