I have been wanting to make use of a pair of 1N5819s to protect an RF amplifier I am building from static discharge, should someone touch the antenna, but haven't been able to obtain any of these just yet. I DO have some 1N4001s however, and am honestly wondering what advantages the 1N5819s would have over the the more readily available 1N4001s (which are already sitting on my workbench.) I have used 1N5819s in the past, and suspect I have forgotten something, I just can't remember what. What is it that I am missing here? I believe I know what I ought to use, I just can't remember why. Somebody, please, enlighten me, and refresh my failing memory. What characteristic is it that the 1N5819 has that the 1N4001 so obviously lacks? I've looked at the datasheets, but it escapes me. Many thanks for any advice, observations or measningful input. I will probably wait for the
1n5819s, I would just like to remember why...Dave
