TLWY7900

LED Indication - Discrete Overview

The TLWY7900 is a single-color yellow LED manufactured by Vishay Semiconductor Opto Division. It features a non-diffused colorless lens with a dome shape and a 2 mm size. The component utilizes a through-hole mounting style within a 7.62 mm square, 4-pin package. Key electrical parameters include a forward current of 70 mA, a forward voltage of 2.1 V, and a power rating of 187 mW. The optical output specifies an intensity of 0.7 mcd at the rated current, with a peak wavelength of 592 nm.

LED Indication - Discrete Feature Summary

• Features a clear, non-diffused dome-shaped lens for directed light emission
• Designed for through-hole installation in a compact 4-pin square package
• Emits monochromatic yellow light with a specific peak wavelength

LED Indication - Discrete Applications

• Indicator lights for electronic equipment status display
• Panel-mounted visual signaling components
• General-purpose illumination in control interfaces

LED Indication - Discrete Procurement Notes

Verify the exact ordering suffix against the manufacturer's official datasheet to ensure correct binning and packaging specifications. Confirm that the 7.62 mm square 4-pin package matches the target PCB footprint requirements. Cross-reference the RoHS compliance status and lead times directly with authorized distributors prior to finalizing procurement plans.

LED Indication - Discrete Selection Notes

Select this component when a distinct yellow indication is required without light diffusion. Ensure the circuit design accommodates the 2.1 V forward voltage drop and limits current to the specified 70 mA maximum. Consider the physical dimensions of the 7.62 mm package for adequate spacing on the assembly board.

LED Indication - Discrete Part Context

This part belongs to Vishay's range of discrete yellow LEDs intended for visual indication applications. It differs from diffused variants by providing a focused beam pattern. The 4-pin through-hole configuration offers robust mechanical stability compared to surface-mount alternatives.

LED Indication - Discrete Replacement Considerations

Consult the official Vishay replacement guide for direct equivalents. Verify compatibility of pinout, forward voltage, and luminous intensity before substituting with other yellow LED models.
