FREDs?

don | FREDs? Mark Baier from Victoria Amps seems to have created a minor sensation with his recent TQR article about using Fast Recovery Epitaxial Diodes as a better-sounding alternative in solid-state rectifier circuits. Like a lot of other folks here, i thought it might be interesting to try it out myself and spoke to my usual parts supplier. He doesn't know from FREDs, but he can get me all the fast-recovery diodes i want. My questions are: The "epitaxial" designation apparently refers to the manufacturing process. Is this something radically different from the way "regular" FRD's are made? Does the epitaxial process produce fast-recovery diodes that sound perceptibly different from the "regular" kind? Is this difference measurable or quantifiable in some way? Would regular fast-recovery diodes be any improvement or should i hold out for FREDs? |
