[sci.electronics] Varo H477 HV Diode

sjb@dalek.UUCP (Seth J. Bradley) (12/25/89)

Could some one please give me the voltage and current
rating of this device?  Also, can an HV diode be tested
with a multimeter in the same fashion as a low voltage one?
thanks in advance!

To answer the second part of your question, the diode will have a fairly
large diode drop across it.  A typical HV rectifier for a modern TV set
is a pencil diode mounted on the flyback.  A pencil diode is a ceramic
tube with a long stack of little discs in it.  Each disk is an individual
diode.  I would guess that a typical modern multimeter would measure
resistence with a voltage below the diode drop of your HV
rectifier, so you would get high resistence in both directions.
