reverse recovery time of 6 kV diodes from All-Electronics

For those of you interested in HV DC supplies, etc... 

Vivek and I just measured (approximately) the reverse recovery time of the
6kV, 200 mA diodes from All Electronics (http://www.allcorp-dot-com/) (part
number R6000, page 80 of catalog 701, $0.50 each, 100 for $40.00).

A lash up test rig with a 1 MHz square wave source at 4.5 Volts into a 50
ohm scope input shows the reverse recovery time is around 110-120 nSec.
Not blindingly fast, but certainly fast enough for line frequency
applications, and potentially fast enough for rectification at TC
frequencies (say, you wanted to build a AC/DC converter in the secondary to
measure voltages or currents).

No idea on the other diode parameters..
