This document describes the features and characteristics of the LATB T66B Hyper Multi TOPLED® enhanced optical Power LED, including its package, device, wavelength, viewing angle, technology, optical efficiency, grouping parameters, processing method, soldering method, pre-treatment, taping, ESD resistance, etc.
The LATB T66B is a multi‑color LED offered in amber, true‑green and blue variants. It features a white P‑LCC‑4 package with a black surface for higher contrast on RGB displays and a diffused resin for additive color mixing. The device emits at peak wavelengths of 617 nm (amber), 528 nm (true‑green) and 470 nm (blue) with a Lambertian viewing angle of 120°.
The datasheet provides detailed electrical ratings such as forward voltage (typ. 2.0 V amber, 3.5 V green, 3.8 V blue), forward current up to 70 mA, and an ESD‑withstand voltage of up to 2 kV. Operating temperature ranges from –40 °C to +100 °C, and optical efficiencies are 24 lm/W (amber), 13 lm/W (green) and 3 lm/W (blue). Ordering codes and grouping information for different luminous intensity groups are also listed. This manual is written in German.
