3YD-201

LED Indication - Discrete Overview

The Bivar Inc. 3YD-201 is a through-hole yellow LED indicator designed for panel or board mounting. It utilizes a T-1 package configuration with a diffused lens to provide wide viewing angles and uniform light distribution. The component operates at a standard forward voltage of 2V, suitable for low-voltage digital logic interfaces. It features a radial lead arrangement compatible with standard PCB layouts.

LED Indication - Discrete Feature Summary

• Diffused lens design ensures uniform light emission and wide viewing angles
• Yellow color output optimized for status indication applications
• Through-hole construction provides secure mechanical retention on printed circuit boards

LED Indication - Discrete Applications

• Panel-mounted status indicators
• Board-level power and activity signaling
• Low-voltage digital equipment monitoring

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version for the 3YD-201 to confirm exact luminous intensity and forward current ratings, as these parameters can vary by manufacturing batch. Ensure compatibility with existing PCB footprints and verify RoHS compliance status against current regulatory requirements before finalizing procurement.

LED Indication - Discrete Selection Notes

Select this component when a diffused yellow indicator is required for clear visibility in various lighting conditions. The T-1 form factor offers a balance between size and brightness. Consider the 2V forward voltage drop when designing the current-limiting resistor network to ensure proper operation within the target system's voltage constraints.

LED Indication - Discrete Part Context

This part belongs to Bivar's discrete LED indication series, focusing on reliable visual signaling components. The 3YD-201 specifically addresses the need for robust, through-hole mounted indicators that offer consistent performance in industrial and consumer electronic assemblies requiring clear visual feedback.

LED Indication - Discrete Replacement Considerations

Cross-reference with other T-1 yellow diffused LEDs from Bivar or alternative manufacturers. Verify pin spacing, lens diameter, and electrical characteristics match the original design requirements before substitution.
