Just curious:
I believe HEXFRED is trademarked by IR?
I worked for IR for years....making among other things HEXFRED diodes. The 'FR' stands for 'fast recovery', right? How does that play into 'soft recovery'?
BTW, ours were made using an Epi substrate.(the 'E' in FRED) Very expensive start material, but we'd made I don't know how many.....certainly in the hundreds...on a 6" wafer.

Given the current state of semiconductor manufacture, these are 'commodity' parts, the only thing to drive up the price is short manufacturing runs and low demand.

IIRC FR rectifiers tend to have much smaller and shorter spikes - Timbo in Oz 22:19:27 07/19/12 (0)
