ISOCOM SFH620A-3X Optocoupler, 1-Channel, DIP, 4-Pin, 50mA
ISOCOM SFH620A-3X 1-channel optocoupler with 5.3kV isolation. DIP package, 50mA forward current, 100% CTR. For industrial control & signal isolation.
The ISOCOM SFH620A-3X is a high-reliability, 1-channel AC input optically coupled isolator, engineered for superior signal isolation in demanding electronic circuits. It consists of inverse parallel infrared light-emitting diodes and an NPN silicon phototransistor, housed in a compact 4-pin DIP package for easy PCB integration. This optocoupler is specifically designed to provide robust electrical isolation, protecting sensitive components from voltage surges and ground loops.
A key feature is its high isolation voltage of 5.3kV, ensuring safe and reliable signal transmission between systems operating at different potentials and impedances. It is 100% tested for all critical electrical parameters, guaranteeing consistent performance and quality. With a forward current (If) of up to 50mA and a low input current requirement of just ±1mA, it offers efficient operation suitable for a wide range of control and interface applications.
Its construction allows it to withstand a collector-emitter voltage (V(br)ceo) of 70V and offers a total power dissipation of 200mW. The device boasts a minimum current transfer ratio (CTR) of 100%, ensuring effective signal coupling. Ideal for industrial environments, this component provides a dependable solution for noise reduction and circuit protection.
