The TLRE27C family of InGaAsP LEDs from Toshiba includes six color variants (red, yellow, green) designed for outdoor message signboards and full‑color panels. The document lists their electrical and optical characteristics, maximum ratings, and handling precautions.
Key specifications such as forward current, forward voltage, power dissipation, luminous intensity and wavelength range are presented, together with recommended soldering conditions and safety notes regarding IR emission and toxic GaAs material.
| Forward current (If) | 50 mA |
|---|---|
| Forward voltage (Vf) | 4 V |
| Power dissipation | 120 mW |
| Typical luminous intensity | 630 (unit unspecified) |
| Soldering temperature limit | 260 °C max |
The maximum forward current is 50 mA.
Use a soldering temperature no higher than 260 °C, with a maximum soldering time of 3 seconds.
Yes, the visible LED lamp also emits some IR light.
