(5.2mm) wide slot. there are 0.055? (1.4mm) wide apertures in front of the senser and emitter. this device?s small size makes it ideal for pc board mounting in confined spaces. for assistance, call clairex. absolute maximum ratings (t a = 25c unless otherwise stated) storage temperatur e ...................................................................... -40 c to +100c operating temperat ure ..................................................................... - 25c to +85c lead soldering temper ature ...................................................... 260c for 3 seconds total power dissipatio n ................................................................................. 100mw led continuous forward dc current (1) .................................................................... 50ma reverse dc voltage .............................................................................................. 5v power dissipation (2) ........................................................................................ 75mw phototransistor collector-emitter breakdown vo ltage .................................................................. 30v collector power dissipation (3) ............................................................................ 75mw notes: 1. derate linearly 0.67mw/c fr om 25c free air temperature to t a = +85c. 2. derate linearly 1.0mw/c fr om 25c free air temperature to t a = +85c. 3. derate linearly 1.0mw/c fr om 25c free air temperature to t a = +85c. clairex reserves the right to make changes at any time to improve design and to provide the best possible product. ? electrical characteristics (t a = 25c unless otherwise noted) symbol parameter min typ max units test conditions input ired v f forward voltage - 1.2 1.4 v i f = 20ma i r reverse current - - 10 a v r = 3v output phototransistor i d collector-emitter dark current - - 100 na v ce = 10v, e e = 0 coupled v ce(sat) collector-emitter saturation voltage - - 0.4 v i c = 0.1ma, i f = 20ma i c(on) collector current 0.5 - - ma i f = 20ma, v ce = 5v t r , t f output rise and fall time - 20 - sec i c = 0.1ma, v ce = 5v, r l =1k ? , revised 12 / 01 / 04 0.275 0.23 (7.0) (5.8) 0.068 (1.72) 0.020 (0.50) square 0.50 min.
