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.
Multi-leaded power packages commonly have more than three leads; nine-, thirteen- and fifteen-lead units are common, units with five or seven leads with TO-220 style are also manufactured. A notable characteristic is a metal tab with a hole, used in mounting the case to a heatsink. The physical view of multi-leaded power packages are simply ...
A WL-CSP or WLCSP package is just a bare die with a redistribution layer (or I/O pitch) to rearrange the pins or contacts on the die so that they can be big enough and have sufficient spacing so that they can be handled just like a BGA package. [19] PMCP: Power mount CSP (chip-scale package) Variation of WLCSP, for power devices like MOSFETs.
Transistors and ICs of these types cannot handle as much power as higher-power equivalents, such as the TO-220, and can burn out quickly if they dissipate excessive power. There is no standard pinout for the TO-92. The American BJTs use the E-B-C pinout while their Japanese counterparts use the E-C-B pinout and some RF devices use the B-E-C pinout.
7805 in TO-220 and TO-92 packages Internal die of a Tesla MA7805. 78xx (sometimes L78xx, LM78xx, MC78xx...) is a family of self-contained fixed linear voltage regulator integrated circuits. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost.
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).

It’s energy efficient and plugs into a regular 110- or 220-volt power outlet, and it can typically be installed in one day, so you’ll have an elevator up and running with minimal inconvenience.
[1] [2] They are similar to the earlier TO-220-style packages intended for high power dissipation [2] [4] but lack the extended metal tab and mounting hole, while representing a larger version of the TO-252, also known as DPAK, SMT package. As with all SMT packages, the pins on a D2PAK are bent to lie against the PCB surface. The TO-263 can ...
