LB-402DD ROHM

LB-402DN Series LED displays High efficiency, two-digit numeric displays LB-402DN Series z Dimensions (Unit : mm) The LB-402 DN series were designed to meet the need for multi-digit numeric displays. 24.0 These LED numeric displays use GaAsP on 12.0 10 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 10.16 mm. 1.0 2- 1.0 5.57 z Features 1) Height of character : 10.16 mm 2) Common anode and common cathode 0.5 (2.54) configurations are available for each color. (20.32) 3) The package surface is painted black and Tolerances are 0.2 unless otherwise noted: the segments are colored the display color. 4) High efficiency reflectors are used to achieve a bright, clear display. z Selection guide Emitting color Red Orange Yellow Green Common Anode LB-402VD LB-402DD LB-402YD LB-402MD Cathode LB-402VN LB-402DN LB-402YN LB-402MN Order-based production. z Pin assignments 18 17 16 15 14 13 12 11 10 + + ++ +++++ Pin No. Function Pin No. Function a1 a2 1 Segmente1 10 Segmentb2 2 Segmentd1 11 Segmenta2 f1 b1 f2 b2 3 Segmentc1 12 Segmentf2 g1 g2 4 D.P1 13 Digit 2 Common e1 c1 e2 c2 5 Segmente2 14 Digit 1 Common d1 d2 6 Segmentd2 15 Segmentb1 7 Segmentg2 16 Segmenta1 Digit 1 Digit 2 D.P1 D.P2 8 Segmentc2 17 Segmentg1 + ++ + + + + + + 9 D.P2 18 Segmentf1 Pin No. 1 2 3 4 5 6 7 8 9 Rev.A 1/3 1.0 3.5Min. 7.0 10.16 18.0 0.25 (15.24)LB-402DN Series LED displays z Internal circuit schematic (example of common anode) Dig.1 COM Dig.2 COM 14 13 g g a1 b1 c1 d1 e1 f1 1 D.P1 a2 b2 c2 d2 e2 f2 2 D.P2 16 15 3 2 1 18 17 4 11 10 8 6 5 12 7 9 z Absolute maximum ratings (Ta = 25C) Red Orange Yellow Green Parameter Symbol Unit LB-402VD / VN LB-402DD / DN LB-402YD / YN LB-402MD / MN Power dissipation PD 640 640 640 960 mW Power dissipation PD / seg 40 40 40 60 mW Forward current IF 15 15 15 20 mA Peak forward current IFP 60 60 60 60 mA Reverse voltage VR 3 3 3 3 V Operating temperature Topr 25~+75 C Storage temperature Tstg 30~+85 C Pulse width 1ms duty 1 / 5 z Electrical and optical characteristics (Ta = 25C) Red Orange Yellow Green Parameter Symbol Conditions Unit Min.
