replacement diodes for 1N4007

jarthel · 8th June 2002, 10:54 AM

My CD player is using these diodes in the power supply. Can someone suggest a better replacement? How about those high speed soft recovery diodes from Percy audio?
Thanks for the reply.

jarthel:

Try the UF4007: same voltage and current rating, but with 75ns reverse recovery time and soft recovery charasteristics.

I tested different types, the best (lowest switch noise) was the BA159 (also 1A rating as 4007)

In what application did you use these diodes for?

Thanks

The rating of BA150 is 0,5A (max. average rect.)

For testing i made a setup: trafo/diode/1000u cap/load to simulate any ps; tested size and speed of switch-off noise of some diodes like 1Nxxx, BA159, schottky; the applikation was a preamp supply; btw rating of BA159 is: 1A rms, 35A pk, 1000V, cap 18pF, switch-off time 100ns;

Alf, can you list the diodes you tested in this experiment as a starting point for others?

Thanks,

James

Good info.

A quick look online says NA sources are Mouser and MCM.
