VISHAY SFH610A-2 4-Pin DIP Optocoupler, 60mA, 5.3kV

The VISHAY SFH610A-2 is a high-performance, 1-channel phototransistor output optocoupler designed for reliable signal isolation. It features a gallium arsenide (GaAs) infrared diode emitter optically coupled to a silicon planar phototransistor detector, ensuring efficient signal transmission between two electrically isolated circuits. This configuration provides a high current transfer ratio (CTR), low coupling capacitance, and a high isolation voltage for enhanced performance and safety.

Engineered for high reliability, this optocoupler offers excellent CTR linearity relative to forward current, a low saturation voltage, and fast switching times. It is designed to maintain stable operation across a range of temperatures and exhibits low CTR degradation over time. The device also provides high immunity to common-mode interference, making it suitable for noisy electrical environments.

With an end-stackable DIP package featuring a standard 2.54mm pin spacing, it is easy to integrate into various circuit board designs. It complies with the reinforced insulation standards of IEC 60950 (DIN VDE 0805) for operational voltages up to 400VRMS or DC, supported by creepage and clearance distances greater than 8mm. This makes it a robust choice for applications requiring dependable electrical isolation and signal integrity.
