You can solder/clip wires to the terminals and insert the wires into the breadboard/board. Adding a heatsink would be done in a similar fashion as you'd use for the final assembly. If you're using a solderless prototyping board, take care in how much current you allow in the transistor. I've acquired several second hand solderless breadboards that look like they were abused in this manner.How do I attach TO-3 ICs like this one to a prototyping board or pc board and add a heat sink?
thanks "a picture is worth 1000 words"

Attaching wires to the leads of TO-3 devices is quite common as that's usually how they're attached in finished products.
thanks i was wondering about electrical isolationYou can use TO-3 mounting kit that includes a mica washer and nylon sleeves. This keeps the device insulated from the heat sink.
If you don't need the heatsink to be electrically isolated from the IC then just mount the device directly on the sink with a thin layer of thermal grease.You can use TO-3 mounting kit that includes a mica washer and nylon sleeves. This keeps the device insulated from the heat sink.
I am using a ac adaptor to a dc-dc converter instead, thanks.TO3 devices have become very expensive, see below, and as such their use is diminishing rapidly. Mounting hardware used to be ubiquitous, but I haven’t checked in a while. Suggest that you procure something.
