Need some help to identify a component

Can anyone help with this:

It is in a T0-220 package (of sorts - 5 leads coming from the bottom vs 3) and has the following markings:

~ 8612 (there are 2 ~ one just below the first one, unable to display it in a text message - the 'humps' are a bit more pronounced). 1573 REL

thanks for any help or cross reference to it. Tim

The 8612 could be the date? eg week 12 of 1986 perhaps.

Looks like I was wrong about it being a NS part... See this page...
