The TO-220 package is a "power package" intended for power semiconductors and an example of a through-hole design rather than a surface-mount technology type of package. TO-220 packages can be mounted to a heat sink to dissipate several watts of waste heat. On a so-called "infinite heat sink", this can be 50 W or more.
TO-220: Through-hole plastic package with a (usually) metal heat sink tab and three leads TO-226 [ 23 ] TO-247 : [ 24 ] Plastic-encapsulated package with three leads and a hole for mounting on a heat sink
Vishay Semiconductor have released 20W resistors in TO-220 form. so this indicates the expected heat dissipation of the package with a heatsink. source: "TPR Thick Film Technology 20 Watt Power Resistors TO-220 Package". there are 50W zeners in TO-3, and 10W in DO-4, 100W in DO-5 (for comparison).

The heat sink thermal resistance model consists of two resistances, namely the resistance in the heat sink base, , and the resistance in the fins, . The heat sink base thermal resistance, , can be written as follows if the source is a uniformly applied the heat sink base. If it is not, then the base resistance is primarily spreading resistance:
The metal package can be attached to a heat sink, making it suitable for devices dissipating several watts of heat. Thermal compound is used to improve heat transfer between the device case and the heat sink. Since the device case is one of the electrical connections, an insulator may be required to electrically isolate the component from the ...
A thermal interface material (shortened to TIM) is any material that is inserted between two components in order to enhance the thermal coupling between them. [1] A common use is heat dissipation, in which the TIM is inserted between a heat-producing device (e.g. an integrated circuit) and a heat-dissipating device (e.g. a heat sink).
Jonathan India is a solid player, and his best tool has always been his bat, with an ability to get on base at a high clip, but the past few seasons in Cincinnati, finding a spot for him in the ...
HTSOP (Heatsink TSOP) is a variant of TSOP with an exposed pad on the bottom side. [ citation needed ] The pad is soldered to the PCB to transfer heat from the package to the PCB. Similar packages
