This document details the technical specifications of the 20mm seven-segment display products, including colors, packages, pins, features and characteristics.
The HDSP series are 20 mm (0.8 in.) LED seven‑segment displays designed for viewing distances up to 10 metres (33 ft). They use an industry‑standard package and pinout and are offered in both common‑anode and common‑cathode configurations. The series includes multiple color options (Red, AlGaAs Red, High‑Efficiency Red, Yellow, Green) and feature options such as left‑hand/right‑hand decimal points and overflow characters.
The handbook contains technical data, package dimensions, absolute maximum ratings, electrical/optical characteristics, and handling guidelines. It also references application notes for contrast enhancement (Note 1015) and LED soldering (Note 1027).
