Agilent optocouplers can safely withstand a continuous voltage up to either 800 Vac, or 1000 Vdc. Before discussing the high-voltage stress test details, it is worthwhile to define some of the common
The Agilent optocouplers tested in this study have been proved to withstand a continuous voltage of either 800 Vac, or 1000 Vdc, and this allows Agilent optocouplers to be safely used in a wide array of
Generally, this voltage depends on the reverse withstand voltage between the emitter and base of the phototransistor and is low. If a reverse voltage that
Mainly, optical isolation offers high electrical isolation values, an effective "line in the sand" barrier that hazardous voltages are incapable of penetrating. In the case
Much of the technical emphasis has been on the ability of optocouplers to withstand one-time short-term high-voltage transients (e.g., U.L. 1 minute dielectric voltage withstand rating).
In order to design a functionally robust and reliable application with optocouplers, it is essential to understand not only the device''s main parameters and parasitic elements, but also their tolerances
Optocouplers are used in many electronic devices, from mobile electronics to household electronics. So, in this article, let''s learn more about
