| LB-502DN Series LED displays High efficiency, two-digit numeric displays LB-502DN Series The LB-502DN series were designed to meet the need for multi-digit numeric displays. These LED numeric displays use GaAsP on GaP for the emitting material (with the exception of green) and are housed in an epoxy resin package. They are two-digit displays with a character height of 13.0mm. !External Dimensions (Units: mm) 25.0 12.7 10 1.25 !Features 1) Height of character: 13.0mm 2) Common anode and common cathode configurations are available for each color. 3) High efficiency reflectors are used to achieve a bright, clear display. 4) The package surface is painted black and the segments are colored the display color. 1.25 7.4 2-1.25 (20.32) Tolerances are 0.2 unless otherwise noted : !Selection guide Emitting color Red Common Anode LB-502VD LB-502DD LB-502DN LB-502MD LB-502MN Orange Green LB-502VN Cathode Order-based production. !Pin assignments 18 17 16 15 14 13 12 11 10 + + + + + + + + + a1 a2 f1 g1 e1 d1 Digit 1 D.P1 + + + + 2 3 4 5 c1 e2 d2 Digit 2 D.P2 + + + 7 8 9 b1 f2 g2 c2 b2 Pin No. 1 2 3 4 5 6 7 8 9 Function Segment "e1" Segment "d1" Segment "c1" D.P1 Segment "e2" Segment "d2" Segment "g2" Segment "c2" D.P2 Pin No. 10 11 12 13 14 15 16 17 18 Function Segment "b2" Segment "a2" Segment "f2" Digit 2 Common Digit 1 Common Segment "b1" Segment "a1" Segment "g1" Segment "f1" + Pin No. 1 + 6 3.5Min. 0.5 (2.54) 7.0 0.25 (15.24) 13.0 17.5 LB-502DN Series LED displays !Internal circuit schematic (example of common cathode) Dig.1 14 COM Dig.2 13 COM a1 b1 c1 d1 e1 f1 g1 D.P1 16 15 3 2 1 18 17 4 a2 b2 c2 d2 e2 f2 g2 D.P2 11 10 8 6 5 12 7 9 !Absolute maximum ratings (Ta=25C) Parameter Power dissipation Power dissipation Forward current Peak forward current Reverse voltage Operating temperature Storage temperature Symbol PD PD / seg IF IFP VR Topr Tstg Red Orange Green Unit mW mW mA mA V C C LB-502VD / VN LB-502DD / DN LB-502MD / MN 960 60 20 60 5 960 60 20 60 5 -25+75 -30+85 960 60 20 60 5 Pulse width 1ms duty 1 / 5 !Electrical and optical characteristics (Ta=25C) Parameter Forward voltage Reverse current Peak wavelength Spectral line half width Symbol Conditions Min.
