RPT-38PB3F sensors 1/2 phototransistor, top view type RPT-38PB3F the RPT-38PB3F is a silicon planar phototransistor. since it is molded in plastic with a visible light filter, there is almost no effect from stray light. it is particularly suited for use with a rohm sir-34st3f infrared light emitting diode. ! ! ! ! application optical control equipment receiver for sensors ! ! ! ! features 1) high sensitivity. 2) almost no effect from stray light. ! ! ! ! external dimensions (units : mm) 3.1 0.2 ? 0.3 + 0.1 3.4 1.1 max.1 2.5 1 5.2 0.3 min.24 4 ? 0.6 2 ? 0.5 (2.5) emitter collector notes: 1. unspecified tolerance shall be 0.2 . 2. dimension in parenthesis are show for reference. 1 1 2 2 internal connection diagram ! ! ! ! absolute maximum ratings (ta = 25 c) parameter symbol i c v ceo p c v eco topr tstg limits ? 25~ + 85 ? 30~ + 100 32 5 30 150 unit v v ma mw c c collector-emitter voltage emitter-collector voltage collector current collector power dissipation operating temperature storage temperature ! ! ! ! electrical and optical characteristics (ta = 25 c) parameter symbol i c i ceo p v ce(sat) 1 / 2 t r t f min. 2.0 ? ? ? ? ? typ. ? ? 800 ? 36 10 max. ? 0.5 ? 0.4 ? ? unit ma v ce = 5v, e = 500l x v ce = 10v(black box) ? i c = 1ma, e = 500l x ? v cc = 5v, i c = 1ma, r l = 100 ? a nm v deg s conditions light current dark current peak sensitivity wavelength collector-emitter saturation voltage half-angle response time
