This is the specification sheet of Toshiba's InGaAℓP LED TLRE53T,TLRME53T,TLSE53T,TLOE53T,TLYE53T, TLPYE53T,TLGE53T,TLFGE53T,TLPGE53T panel circuit indicators.
The TL53T family comprises a range of InGaAsP LED devices offered in six colors (red, orange, yellow, pure yellow, green, pure green). They are intended for applications such as message boards, security devices, and dashboard displays.
The document lists maximum ratings (50 mA forward current, 4 V reverse voltage, 120 mW power dissipation), electrical and optical characteristics (typical emission wavelengths from 558 nm to 630 nm, luminous intensities up to 476), and handling precautions including a 260 °C maximum soldering temperature. Restrictions note that the parts are not suitable for safety‑critical or high‑reliability equipment such as medical or aerospace instruments.
