SIR-320ST3F_1

SIR-320ST3F Sensors Infrared light emitting diode, top view type SIR-320ST3F The SIR-320ST3F is a GaAs infrared light emitting diode housed in clear plastic. This device has a high luminous efficiency and a 940nm spectrum suitable for silicon detectors. It is small and at the same time has a wide radiation angle, marking it ideal for compact optical control equipment. Applications Optical control equipment Light source for remote control devices Dimensions (Unit : mm) φ3.8±0.3 φ3.1±0.2 Notes: 1. Unspecified tolerance shall be ±0.2. 2. Dimension in parenthesis are show for reference. 5.2±0.3 Min.24 Features 1) Compact (φ3.1mm). 2) High efficiency, high output PO=9.0mW (IF=50mA). 3) Wide radiation angle θ=±18deg. 4) Emission spectrum well suited to silicon detectors (λP=940nm). 5) Good current-optical output linearity. 6) Long life, high reliability. 2 1 (2.5) 2±0.2 2.5±1 2− 0.5 Max.1 4−0.6 1.1 1 Anode 2 Cathode Absolute maximum ratings (Ta = 25°C) Parameter Forward current Reverse voltage Power dissipation Pulse forward current Operating temperature Storage temperature ∗ Pulse width=0.1msec, duty ratio 1% Symbol IF VR PD IFP∗ Topr Tstg Limits 75 5 100 0.5 −25 to +85 −40 to +85 Unit mA V mW A °C °C Rev.B 1/3 SIR-320ST3F Sensors Electrical and optical characteristics (Ta = 25°C) Parameter Optical output Emitting strength Forward voltage Reverse current Peak light emitting wavelength Spectral line half width Half-viewing angle Pesponse time Cut-off frequency Symbol PO IE VF IR Min. − 5.6 − − − − − − − Typ. 9 − 1.2 − 940 40 ±18 1.0 1.0 Max. − − 1.5 10 − − − − − Unit mW mW/sr V µA nm nm deg µs MHz IF=50mA IF=50mA IF=50mA VR=3V IF=50mA IF=50mA IF=50mA IF=50mA IF=50mA Conditions λP ∆λ θ1 / 2 tr·tf fC Electrical and optical characteristic curves FORWARD CURRENT : IF (mA) 100 −25°C 0°C 25°C 50°C 75°C RELATIVE OPTICAL OUTPUT : PO (%) 2 100 FORWARD CURRENT : IF (mA) 100 80 60 40 80 80 60 60 40 40 20 20 20 0 850 0 −20 0 20 40 60 80 100 00 1 FORWARD VOLTAGE : VF (V) 900 950 1000 1050 AMBIENT TEMPERATURE : Ta (°C) OPTICAL WAVELENGTH : λ (nm) FIg.1 Forward current falloff Fig.2 Forward current vs. forward voltage Fig.3 Wavelength 50 EMITTING STRENGTH : IE (mW/sr) RELATIVE EMITTING STRENGTH : IE (%) 200 40 100 50 30 20 20 10 −20 0 20 40 60 80 100 10 0 0 20 40 60 80 100 FORWARD CURRENT : IF (mA) AMBIENT TEMPERATURE : Ta (°C) Fig.4 Emitting strength vs. forward current Fig.5 Radiant intensity vs. ambient temperature Rev.B 2/3 SIR-320ST3F Sensors RELATIVE EMITTING STRENGTH (%) RELATIVE EMITTING STRENGTH (%) 20° 30° 40° 50° 60 60° 70° 80° 90° 100 40 80 10° 0° 100 20 80 60 40 20 0 0 10° 20° 30° 40° 50° 60° 70° 80° 90° ANGULAR DISPLACEMENT : θ(deg) RELATIVE EMITTING STRENGTH (%) Fig.6 Directional pattern 20° 30° 40° 50° 10° 0° 100 80 no masking 60° 70° 80° 90° 100 60 40 20 80 60 40 20 0 0 10° 20° 30° 40° 50° 60° 70° 80° 90° ANGULAR DISPLACEMENT : θ(deg) RELATIVE EMITTING STRENGTH (%) Fig.7 Directional pattern Rev.B 3/3 Appendix Notes No technical content pages of this document may be reproduced in any form or transmitted by any means without prior permission of ROHM CO.,LTD.
