Description
The MAN3900A Series is a High Efficiency Red LED display. Standard units are also available in Red, Green, Orange and Yellow,
with common anode right hand decimal, common anode left hand decimal and common cathode right hand decimal. They can be
mounted in arrays with 0.400-inch (10.16 mm) center-to-center spacing. Units are constructed with Red face and segment color.
Features
• Common anode or common cathode models
• High Efficiency Red
•Fast switching — excellent for multiplexing
•Low power consumption
• Bold solid segments that are highly legible
• Solid state reliability — long operation life
• Impact resistant plastic construction
• Directly compatible with integrated circuits
• High brightness with high contrast
• Categorized for Luminous Intensity (See Note 6)
• Standard dual-in-line package configuration
• Wide angle viewing...150°
• These devices have a Red face and Red segments
Applications
For industrial and consumer applications such as:
• Digital readout displays
• Instrument panels
•Point of sale equipment
• Calculators
• Digital clocks

HIGH EFFICIENCY RED MAN3900A SERIES
Notes:
1. The digit average Luminous Intensity is obtained by summing the Luminous Intensity of each segment and dividing by the total
number of segments. Intensity will not vary more than ±33.3% between all segments within a digit.
2. The curve in Figure 3 is normalized to the brightness at 25°C to indicate the relative Luminous Intensity over the operating
temperature range.
3. The decimal point is designed to have the same surface brightness as the segments, therefore, the Luminous Intensity of the
decimal point is .3 times the Luminous Intensity of the segments, since the area of the decimal point is .3 times the area of the
average segment.
4. Leads of the device immersed to 1/16 inch from the body. Maximum device surface temperature is 140°C.
5. For flux removal, Freon TF, Freon TE, Isoproponal or water may be used to their boiling points.
6. All displays are categorized for Luminous Intensity. The Intensity category is marked on each part as a suffix letter to the part
number.
