The VEMD10940F is part of the Vishay VEMD series of high brightness LED displays. It is a 14.2 mm (0.56 inch) three-segment display with a red GaAsP (Gallium Arsenide Phosphide) dome chip that provides a wide viewing angle and a strong, consistent readability even in the brightest of light conditions. The VEMD10940F is an “asynchronous” display, meaning that the segments within a single display are not perfectly synchronized, but are still capable of displaying characters by using corresponding signal lines. The VEMD10940F has an operating temperature range of -40°C to 85°C and a storage temperature range of -55°C to 110°C. It has a forward current of 15 mA, reverse voltage of 5V, and a typical forward voltage of 1.9V at 15 mA. It is RoHS compliant and has a maximum 3/10” lead length.
