Diode question... SR206 bad or good?
« on: June 26, 2015, 07:49:09 pm »
I am trying to trouble shoot a board and was checking the diodes and came to this one that the reading is not as I think it should be.
It is an SR206 A11 (black w/silver band)
In google it pulls up a data sheet for a schottky.....
I get a .198 reading using the Fluke 87V....
I am getting a .4 range on all the other diodes on the board but I was not sure on a Schottky if it is expected to show similar good range as the other types.
I pulled it out of circuit to test because it is beside a coil and reads both ways when in circuit.
if I reverse polarity it holds the OL reading as it should...

Any help appreciated... I looked at the datasheet but am still too green to decipher more than the obvious  :-//
(I don't have a replacement but I don't want to put a bad part back in either)

Thanks a mill....

Schottky diodes generally have about half the forward voltage of ordinary silicon PN diodes, so all things being equal, it looks OK.

Thanks and I had finally found the same conclusion on G search....... I was sorta hoping that was the trouble so back to the scratch and sniff hunt
