The EL3H7B is a phototransistor optocoupler manufactured by Everlight Electronics, packaged in a compact 4-pin SSOP with a 2.0 mm profile. It consists of an infrared emitting diode optically coupled to a phototransistor detector, encapsulated in a green compound. The device provides a high isolation voltage of 3750 Vrms between input and output, ensuring reliable signal isolation in various applications.
Key electrical specifications include a current transfer ratio (CTR) of 50% to 600% at IF=5mA, VCE=5V, and 40% to 320% at IF=10mA, VCE=5V. The maximum collector-emitter voltage is 80 V, and the maximum emitter-collector voltage is 7 V. The forward voltage is typically 1.2 V to 1.4 V at 20 mA. The device operates over a temperature range of -55°C to +110°C and is suitable for DC-DC converters, programmable controllers, and telecommunication equipment.
The EL3H7B is RoHS3 compliant, REACH unaffected, and halogen-free (Br <900 ppm, Cl <900 ppm, Br+Cl <1500 ppm). It is approved by UL, cUL, VDE, SEMKO, NEMKO, DEMKO, FIMKO, and CQC. The moisture sensitivity level is MSL 1 (unlimited).
