15N20 is an n-channel power MOSFET device mainly used for converters and power applications, it had two sets of device coverings such as TO-220 & TO-251 packages.
TO-220 & TO-251 are the through-hole three terminal package which is made of epoxy/plastic materials for higher temperature capacity.
The TO-220 package had the provision to attach the heat sink with it for heat transfer purposes, but the TO-251 package doesn’t have a hole at them for attachment purposes.
