ld-603 series led displays flat displays ld-603 series the ld-603 series were designed in response to the need for large, flat displays. these are two-chip, flat displays with high luminance. ! features 1) 6.8 13.8mm planar emission from two chips connected in series. 2) high luminance, uniform planar emission 3) thin outer casing, multiple units can be coupled together. 4) four colors are available : red, orange, yellow and green. ! ! ! ! external dimensions (units : mm) tolerances are ?.3 unless otherwise noted : (1.8) 0.3 0.6 (0.7) (2.5) (2.5) 6.7 0.5 5.6 0.2 0.6 15.0 13.8 0.2 6.8 0.2 8.0 cathode mark pin no.1 2 3 pin no.1 2 3 ! ! ! ! selection guide red ld-603vr orange LD-603DU ? yellow ld-603yy ? green ld-603mg emitting color type ? order-based production. ! ! ! ! absolute maximum ratings (ta=25 c) parameter symbol red unit ld-603vr orange LD-603DU yellow ld-603yy green ld-603mg mw ma ma v ?c ?c p d i f i fp v r topr tstg power dissipation forward current peak forward current reverse voltage operating temperature storage temperature 120 20 60 ? 60 ? 60 ? 60 ? 3 120 20 3 120 20 3 150 25 3 ? 25 + 75 ? 30 + 85 ? pulse width 1ms duty 1 / 5
