This document describes a PLCC-4 surface mount tricolor LED with high brightness and reliability, suitable for indoor and outdoor full color display applications.
The ASMT‑QTB0‑0AA02 is a surface‑mount tricolor LED packaged in an industry‑standard PLCC‑4 package with added heat‑sinking capability. It offers high brightness, a wide 120° viewing angle, and a black top surface for better contrast, making it suitable for indoor and outdoor full‑color signage.
The datasheet lists electrical and optical characteristics such as typical forward voltages (1.80 V red, 2.80 V green/blue), peak forward current of 100 mA, power dissipation up to 120 mW, and operating temperature range from –40 °C to +110 °C. It also includes handling precautions for moisture‑sensitive devices and recommended reflow soldering profiles.
| Package type | PLCC‑4 |
