1N825A 6.2v ref. diode wanted.

[rg26ce1991@hotmail.com]

Greetings group.
Can someone please tell me where I can get a 1N825A.

Data sheets on the web tell me it is a 6.2v temperature compensated
zener.

Thanks in advance.
Russell Griffiths.

Thanks Brian.
I think both Radio Spares and Farnell sell 1N821 which is equivalent to
1N827.

Can you please tell me if this type of diode can be tested the same as
a regular zener using the diode check on a multimeter?

My meter shows the 1N825A diode I have here to be open circuit both
ways.

Should the meter read open/~600mV like a regular zener?

Can you tell me what the difference is between 1N827 and 1N827A?
Other numbers have the "A" added as well.

Thanks for the offer.
I may send you my address, but I am having email problems at the
moment.

Thanks,
Russell Griffiths.

.... only as far as the nominal reference voltage. The bigger 1N82x
numbers have much tighter tolerances.

I don't know.

Test the zener voltage with a 9V battery and a 390 ohm series
resistor.

Should the meter read open/~600mV like a regular zener?

According to the datasheet, "A" parts have a lower differential
resistance.
