LA-301BB

LA-301 B / L Series LED displays Single Digit LED Numeric Display LA-301 B / L Series LA-301 B / L series is developed because of the demand for small single digit LED Numeric Display. Materials of emission are GaAsP on GaP, AlGalnP, GaP and GaN. This is the height of a letter 8mm, single digit LED Numeric Display that is packed by epoxy resin. Dimensions (Unit : mm) 7.0 10˚ 1.0 Features 1) The height of a letter is 8mm. 2) The light don’t leak from the segment in spite of the small package. 3) The package of surface color is black. Color of segment is colored in emitting color. (Blue color is only milky white) 4) Each color has anode common and cathode common respectively. 0.1 0.5 +0 1.0 4.0 φ0.8 (5.3) Selection guide Emitting color Common Anode Cathode Red LA-301VB LA-301VL Red Orange Yellow (High brightness) (High brightness) (High brightness) LA-301AB LA-301AL LA-301EB LA-301EL LA-301XB LA-301XL 3.8±0.5 0.1 0.25 +0 5.0 Tolerance are ±0.3 unless otherwise noted: Green LA-301MB LA-301ML Blue LA-301BB LA-301BL Pin assignments Pin No. 1+ 2+ 3+ 4+ 5+ e d D.P f g c a b + 10 +9 +8 +7 +6 Pin No. 1 2 3 4 5 6 7 8 9 10 Function Segment "a" Segment "f" Segment "g" Segment "e" Segment "d" D.P Cathode D.P Anode Segment "c" Common Segment "b" Equivalent circuit (anode common) COM 9 7 (cathode common) COM 9 7 abcdefg 1 10 8 5 4 2 3 D.P 6 abcdefg 1 10 8 5 4 2 3 D.P 6 Rev.C (2.0) (8.0) 11.0 8.0 1/4 LA-301 B / L Series LED displays Absolute maximum ratings (Ta=25°C) Parameter Power dissipation Power dissipation Forward current Peak forward current Reverse voltage Operating temperature Storage temperature ∗1 Pulse width 1ms Duty 1 / 5 ∗2 Pulse width 0.1ms Duty 1 / 10 Symbol PD PD / seg IF IFP VR Topr Tstg Orange Yellow Red Blue Green (High brightness) (High brightness) (High brightness) LA-301VB / VL LA-301AB / AL LA-301EB / EL LA-301XB / XL LA-301MB / ML LA-301BB / BL 480 336 320 520 520 520 60 42 40 65 65 65 20 10 15 25 25 25 60 ∗1 50 ∗2 60 ∗1 50 ∗2 50 ∗2 50 ∗2 5 5 5 5 5 5 −25 to +75 −30 to +85 Red Unit mW mW mA mA V ˚C ˚C Electrical characteristics (Ta=25°C) Parameter Forward voltage Reverse current Peak wavelength Spectral line half width Symbol Conditions Orange Yellow Red (High brightness) (High brightness) (High brightness) Typ.
