Vishay, IL300-F-X007 Photodiode Output Optocoupler, Through Hole, 8-Pin SMD / 1808278

The IL300 linear optocoupler consists of an AlGaAs IRLED irradiating an isolated feedback and an output PIN photodiode in a bifurcated arrangement. The feedback photodiode captures a percentage of the LEDs flux and generates a control signal (IP1) that can be used to servo the LED drive current. This technique compensates for the LED’s non-linear, time, and temperature characteristics. The output PIN photodiode produces an output signal (IP2) that is linearly related to the servo optical flux created by the LED. The time and temperature stability of the input-output coupler gain (K3) is insured by using matched PIN photodiodes that accurately track the output flux of the LED.FEATURES • Couples AC and DC signals • 0.01 % servo linearity • Wide bandwidth, > 200 kHz • High gain stability, ± 0.005 %/°C typically • Low input-output capacitance • Low power consumption, < 15 mW • Isolation rated voltage 4420 VRMS • Internal insulation distance, > 0.4 mm APPLICATIONS • Power supply feedback voltage / current • Medical sensor isolation • Audio signal interfacing • Isolated process control transducers • Digital telephone isolation AGENCY APPROVALS • UL • cUL • DIN EN 60747-5-5 (VDE 0884-5) available with option 1 • BSI • FIMKO • CQC
