3SRD

LED Indication - Discrete Overview

The Bivar Inc. 3SRD is a T-1 (3mm) super red discrete LED designed for through-hole mounting. It features a diffused lens with a dome shape and emits light at a wavelength of 645 nm. The component operates with a forward voltage of 1.7 V and a forward current of 20 mA, supporting a power rating of 70 mW. Typical luminous intensity is rated at 40 mcd.

LED Indication - Discrete Feature Summary

• Through-hole radial lead configuration for standard PCB mounting
• Diffused dome lens design for wide viewing angle illumination
• Super red emission optimized for high visibility applications

LED Indication - Discrete Applications

• Panel mount status indicators
• General purpose circuit board indication
• Visual signaling in electronic equipment

LED Indication - Discrete Procurement Notes

Verify the specific suffix variant required, as the base model number corresponds to different packaging or accessory configurations such as bulk discrete units or assemblies with wires. Confirm RoHS compliance status directly from the manufacturer datasheet prior to ordering. Ensure the selected variant matches the intended mechanical assembly requirements for the target application.

LED Indication - Discrete Selection Notes

Select this component when a standard 3mm through-hole red indicator is required. Consider the 1.7 V forward voltage drop for circuit design calculations. The diffused lens provides broad visibility compared to clear variants. Verify that the 20 mA maximum forward current aligns with the driving circuit capabilities and thermal management strategy for the final product.

LED Indication - Discrete Part Context

This part belongs to Bivar's line of single-color LEDs, specifically the T-1 form factor series. It serves as a fundamental optical component for visual feedback in electronics. The 3SRD designation identifies the core LED die and lens configuration, distinct from assembled indicators or light pipes offered by the same manufacturer.

LED Indication - Discrete Replacement Considerations

Direct substitutes include the 3SRD-S for bulk discrete packaging or the 3SRD-F for specific radial configurations. Variants like the 3SRD-201 may offer different mounting styles. Always cross-reference pinout and electrical parameters before substitution.
