TLHR4200

LED Indication - Discrete Overview

The TLHR4200 is a high-efficiency red light-emitting diode from Vishay Semiconductor Opto Division, designed for visual indication applications. It features a clear, tinted T-1 (3mm) through-hole package with undiffused optics to provide a focused beam. The device operates at a peak wavelength of 635nm and a dominant wavelength of 619nm, ensuring distinct red coloration. With a typical forward voltage of 2V and a viewing angle of 44 degrees, it offers reliable performance in standard LED indicator circuits.

LED Indication - Discrete Feature Summary

• High-efficiency red emission optimized for visibility
• Clear undiffused T-1 package for directional light output
• Standard 3mm radial lead configuration for easy mounting

LED Indication - Discrete Applications

• Panel status indicators
• Power supply signal lights
• Electronic equipment front panels

LED Indication - Discrete Procurement Notes

Verify the specific suffix or variant against the manufacturer's current datasheet to ensure compatibility with required wavelength and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production assemblies.

LED Indication - Discrete Selection Notes

Select this component when a focused, non-diffused red light source is required for direct visual monitoring. The 44-degree viewing angle suits applications where the indicator is viewed directly rather than through a diffuser. Ensure circuit design accounts for the 2V typical forward voltage drop.

LED Indication - Discrete Part Context

This part belongs to Vishay’s discrete LED portfolio, specifically within the high-efficiency visible spectrum category. It complements other optical components like phototransistors and optocouplers in systems requiring both emission and detection capabilities.
