Motorola MDA980 bridge rectifier |
|
|
Does anyone have any information for the Motorola MDA980-1 bridge
rectifier?
Any information (reverse voltage, average If, etc) would be appreciated. If
anyone knows where I can get a datasheet that would be even better. I've
tried all the online datasheet archives I know and tried several
manufacturers looking for cross references. The closest I've got is a copy
of a Motorola 1994/95 rectifier data book - it's got the MDA970. Earlier
databooks have MDA950, MDA940, etc. so I presume the MDA980 must have been
released just after that databook was published.
Thanks,

I have Motorola's 1984 "Master Selection Guide and Catalog". The
MDA980 and its variants is listed in the index, but there is no page
number, and the devices do not appear in the catalog proper. <shrug>

That part shows as a cross in my ECG book as ECG 5322. 200 PRV 25A.

Ok, thanks. I'd also like to apologise for getting the date wrong, it was a |
1984/85 databook that had MDA970. The 90s book (actually 1992) was a
Motorola rectifier databook that only had two-terminal devices in it.
The 84/5 book I looked at had no mention of the MDA980 at all.

I don't know what "you" looked up, but going to YOUR link, and plugging in
the MDA980-1 as he has listed, it STILL comes out to a 200 PRV 25 Amp
Bridge. The NTE 5322 just as I said. Except my example was an ECG brand. Try
it again!

OK, I see where you went.... You went to the Part Search in top right hand
corner... But, if you go down to the far left, you get the NTE Data Sheet
area. Punch in the same number, and you will see what I found - which is the
same in my ECG book. Kind of strange, such a huge difference in ratings. I
have some Motorola books here, but none to my knowledge have Bridge
Rectifiers in them, just RF modules and transistors.

MDA980-1 through MDA980-6 have increasing Vrrm.
50 - 100 - 200 - 300 - 400 - 600
MDA980 is rated for 12A av.
MDA990 is rated for 30Aav in the 'same' package, but incorporating an
imbedded aluminum mounting interface.
Ifsm is 300A all types.
Rthjc is 11degC/W per diode cell in MDA980. Total effect is 6.05degC/W
" " 6 degC/W " " " " MDA990. Total effect
is 2.28degC/W
Tj max 175degC.
You have the part, so package dimensions are superfluous.
Metal backing on case of MDA990 is isolated to an unspecified voltage.
Maximum mounting torque is 20 in.lb. for 6-32 screw thread, both
packages.
This from the
Motorola Semiconductor Data Library
Vol.3 Series A, 1974.

ECG/NTE parts tend to have ratings which are as good or better than
the original parts. For example, a 200V part will replace a 50V part,
so stocking both parts is unnecessary.

Sorry for the delay in responding.
Thanks for the datasheet it was exactly what I was looking for. Also,
thanks to everyone else who responded.
