The TLGD256 is a two‑chip green LED lamp designed for use in message board applications. It features a clear transparent lens and provides high‑intensity green light emission with a peak wavelength of 567 nm. The device is specified for a forward current of 15‑20 mA (DC) and a forward voltage of about 4.3‑5.4 V at 20 mA.
Key electrical ratings include a maximum forward current of 30 mA, reverse voltage of 8 V, and power dissipation of 170 mW. The lamp operates from –40 °C to 85 °C and can be stored between –40 °C and 120 °C. Soldering should not exceed 260 °C and 3 seconds to avoid damage to the resin package.
