Product Overview
The EVERLIGHT EL_ITR8307-L24-TR8 is a reflective infrared optical switch built around an IR emitter and phototransistor receiver. Its device function is defined as a light reflection switch with a GaAs IR-LED transmitter and NPN phototransistor receiver for infrared-range, short-distance sensing. The selection guide identifies GaAlAs as the IR emitter chip material and silicon as the phototransistor chip material.
Electrical limits include 75 mW input power dissipation, 50 mA input forward current, 5 V input reverse voltage, 1 A peak forward current under the specified pulse condition, 75 mW collector power dissipation, and 50 mA collector current. Output-side voltage ratings include 30 V collector-emitter voltage and 5 V emitter-collector voltage.
At Ta=25°C, the emitter has 1.2 V typical and 1.6 V maximum forward voltage at IF=20 mA, with 940 nm typical peak wavelength. Transfer characteristics include 0.5 mA minimum to 15.0 mA maximum light current and typical 20 us rise and fall times. Assembly guidance includes MSL 4 storage, 72-hour floor life after bag opening, and a reflow soldering limit of not more than two times.
