MDA962-1 is a full wave bridge rectifier rated at 50 PIV and 10 amps. 

1971 prices:

$4.38 for 1 to 9 units
$3.65 for 10 to 24 units
$3.30 for 25 to 99 units
$2.75 for 100 or more units

Imagine what those prices work out to in 2006 dollars.

There was a whole family of these rectifiers, in various ratings. The basic 
part number tells the current capacity, the suffix digit tells the PIV:

MDA962-1  50 PIV
MDA962-2  100 PIV
MDA962-3  200 PIV
MDA962-4  300 PIV
MDA962-5  400 PIV
