The D2PAK, which has a flat heat sink at the back, is basically the surface-mount equivalent of the TO-220 through-hole package and is therefore sometimes referred to as &#8216;SMD-220&#8217;. The D2PAK is also known as &#8216;TO-263<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>Q2: What is the difference between TO-252 and to 263?<\/strong><\/p>\n<p><strong>Answer: <\/strong>Beyond using the same mounting style (surface mounting), they also have the pins bent against the surface of the Printed Circuit Board (PCB). The difference between the TO252 and TO236 semiconductor packages is the size.\u00a0While the TO252 is smaller, the TO263 is bigger<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Q3: What is the difference between TO-220 and D2PAK?<\/strong><\/p>\n<p><strong>Answer: <\/strong>TO-220 and TO-262 (D2PAK) are very similar packages. In fact, you can hand form a D2PAK from a TO-220 by cutting off the clip at the end, and bending the leads. The only difference is\u00a0TO-220 can be bolted down because of the extended tab, where as D2PAK is a surface mount device<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>Q4: What is the difference between D2PAK and D3PAK?<\/strong><\/p>\n<p><strong>Answer: <\/strong>The Decawatt Package 3 , or D3PAK , is a bigger version of the D2PAK package. Just like the D2PAK (and the DPAK, the D2PAK&#8217;s predecessor), the D3PAK is a surface-mount plastic-molded package intended for high-power discrete devices. The D3PAK is also known by other names such as &#8216;TO-268&#8217; and &#8216;Discrete Package 3&#8217;<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>For further question or inquiries, please kindly contact Loie: <a href=\"mailto:order@ufcapacitors.com,\">sales4@topdiode.com,<\/a> or visit our website: <a href=\"http:\/\/www.topdiodes.com\">www.topdiodes.com<\/a> thanks<\/strong><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Topdiode the DPAK (TO-252) package follows the JEDEC standard and is configured for surface mount applications.
