LA-301BB ROHM

LA-301 B / L Series LED displays Single Digit LED Numeric Display LA-301 B / L Series z Dimensions (Unit : mm) 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. 7.0 This is the height of a letter 8mm, single digit LED 10 Numeric Display that is packed by epoxy resin. z Features 1) The height of a letter is 8mm. 1.0 0.8 2) The light dont leak from the segment in spite of the 4.0 small package. 3) The package of surface color is black. Color of segment is colored in emitting color. (Blue color is only +0.1 milky white) 0.25 0 4) Each color has anode common and cathode common (5.3) respectively. Tolerance are 0.3 unless otherwise noted: z Selection guide Emitting color Red Orange Yellow Red Green Blue (High brightness) (High brightness) (High brightness) Common Anode LA-301VB LA-301AB LA-301EB LA-301XB LA-301MB LA-301BB Cathode LA-301VL LA-301AL LA-301EL LA-301XL LA-301ML LA-301BL z Pin assignments Pin No. Function Segment 1 Pin No. 2 Segment 1 + a + 10 3 Segment 4 Segment 2 + + 9 f b 5 Segment 3 + g + 8 6 D.P Cathode 7 D.P Anode 4 + + 7 ec 8 Segment 5 + + 6 d 9 Common D.P 10 Segment z Equivalent circuit (anode common) (cathode common) COM COM 9 7 9 7 g g a b c d e f D.P a b c d e f D.P 1 10 8 5 4 2 3 6 1 10 8 5 4 2 3 6 Rev.C 1/4 1.0 3.80.5 5.0 8.0 11.0 +0.1 0.5 0 (2.0) (8.0)LA-301 B / L Series LED displays z Absolute maximum ratings (Ta=25C) Red Orange Yellow Red Green Blue (High brightness) (High brightness) (High brightness) Parameter Symbol Unit LA-301VB / VL LA-301AB / AL LA-301EB / EL LA-301XB / XL LA-301MB / ML LA-301BB / BL Power dissipation PD 320 520 520 520 480 336 mW Power dissipation PD / seg 40 65 65 65 60 42 mW Forward current I 20 10 mA F 15 25 25 25 1 2 2 2 1 2 Peak forward current IFP 60 50 50 50 60 50 mA Reverse voltage VR 5 5 5 5 5 5 V Operating temperature Topr 25 to +75 C Storage temperature Tstg C 30 to +85 1 Pulse width 1ms Duty 1 / 5 2 Pulse width 0.1ms Duty 1 / 10 z Electrical characteristics (Ta=25C) Red Orange Yellow Red Green Blue (High brightness) (High brightness) (High brightness) Parameter Symbol Conditions Unit Typ.
