This document is a technical specification sheet for the VISHAY TLHK5800 product, including product features, application scenarios, parameters and performance.
The YTLHK5800 is a high‑intensity red LED housed in a 5 mm untinted non‑diffused plastic package. Its very small viewing angle provides extremely high luminous intensity, making it suitable for status lights, indicators, lightpipes, outdoor displays, medical instruments, and other applications.
The datasheet provides comprehensive optical and electrical characteristics, absolute maximum ratings, and package dimensions. Key parameters include luminous intensity, forward voltage, reverse voltage, power dissipation, and temperature limits, all measured under specified test conditions.
| Luminous intensity (20 mA) | 1000‑2500 mcd |
|---|---|
| Dominant wavelength | 630 nm |
| Peak wavelength | 643 nm |
| Forward voltage (20 mA) | 1.9‑2.6 V |
| Reverse voltage | 5 V |
| Junction temperature | 100 °C |
| Operating temperature range | -40 °C to +100 °C |
| Storage temperature range | -55 °C to +100 °C |
| Thermal resistance (junction‑ambient) | 350 K/W |
The YTLHK5800 delivers between 1000 and 2500 mcd at a forward current of 20 mA.
The forward voltage varies from 1.9 V to 2.6 V when measured at 20 mA.
The device can operate from –40 °C up to +100 °C ambient temperature.
