LB-403DN Series LED displays High efficiency, three-digit numeric displays LB-403DN Series !External Dimensions (Units: mm) The LB-403DN 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 three-digit displays with a character height of 10.16 mm. 33±0.15 (12.5) 11.0 10˚ !Features 1) Height of character: 10.16 mm 2) Long 9 mm leads (minimum) on bottom of case. 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. 1.0 0.3 1.0 10.16 16.0 11.0 3−φ1 9Min. 7.0 4.56 0.5 (2.0) (28.0) Tolerances are ±0.2 unless otherwise noted : !Selection guide Emitting color Red Orange Green LB-403VD LB-403DD ∗ LB-403MD − LB-403MN Common Anode LB-403VN Cathode ∗ Order-based production. !Pin assignments 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 + + + + + + + + + + + + + + + a2 a1 f1 e1 f2 b1 g1 g2 e2 c1 c2 3 f3 + + + 4 5 + + + 6 7 g3 e3 b3 c3 d3 Digit 2 D.P2 Digit 1 D.P1 + + + b2 d2 d1 Pin No. 1 2 a3 + Digit 3 D.P3 + + + + + 8 9 10 11 12 13 14 15 Pin No. Function Pin No. Function 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Segment "e1" Segment "d1" Digit 1 Common Segment "c1" D.P1 Segment "e2" Segment "d2" Digit 2 Common Segment "c2" D.P2 Segment "e3" Segment "d3" Digit 3 Common Segment "c3" D.P3 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 Segment "b3" Segment "a3" Digit 3 Common Segment "f3" Segment "g3" Segment "g2" Segment "b2" Segment "a2" Digit 2 Common Segment "f2" Segment "g1" Segment "b1" Segment "a1" Digit 1 Common Segment "f1" LB-403DN Series LED displays !Internal circuit schematic (example of common cathode) Dig.1 COM 3 29 Dig.2 COM 8 24 a1 b1 c1 d1 e1 f1 g1 D.P1 28 27 4 2 1 30 26 5 Dig.3 COM 13 18 a3 b3 c3 d3 e3 f3 g3 D.P3 17 16 14 12 11 19 20 15 a2 b2 c2 d2 e2 f2 g2 D.P2 23 22 9 7 6 25 21 10 !Absolute maximum ratings (Ta=25°C) Parameter Red Symbol Orange Green Unit LB-403VD / VN LB-403DD / DN LB-403MD / MN Power dissipation PD 1344 1344 1344 mW Power dissipation PD / seg 56 56 56 mW Forward current IF Peak forward current IFP 20 60∗ 20 60∗ 20 60∗ mA Reverse voltage VR 5 5 5 V mA Operating temperature Topr −25∼+75 ˚C Storage temperature Tstg −30∼+85 ˚C ∗ Pulse width 1ms duty 1 / 5 !Electrical and optical characteristics (Ta=25°C) Parameter Min.
