2. TO-220 - Wikipedia

   en.wikipedia.org/wiki/TO-220

   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.

3. Multi-leaded power package - Wikipedia

   en.wikipedia.org/wiki/Multi-leaded_power_package

   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.

   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).

6. Zig-zag in-line package - Wikipedia

   en.wikipedia.org/wiki/Zig-zag_in-line_package

   The quad in-line package uses a similar staggered semiconductor package design, but on two sides instead of one. High-power devices (such as high-voltage op-amp ICs, voltage regulators, and motor driver ICs) are still being manufactured in a package with a zig-zag pinout (and normally screwed onto a heatsink).

7. TO-3 - Wikipedia

   en.wikipedia.org/wiki/TO-3

   Size comparison of BJT transistor packages, from left to right: SOT-23, TO-92, TO-126, TO-3 3D model of TO-3 package. In electronics, TO-3 is a designation for a standardized metal semiconductor package used for power semiconductors, including transistors, silicon controlled rectifiers, and, integrated circuits.

   The packages were received around 30 minutes apart from each other, and one looked similar to a suspicious package received by an election office in another state.

9. TO-5 - Wikipedia

   en.wikipedia.org/wiki/TO-5

   Several variants of the original TO-5 package have the same cap dimensions but differ in the number and length of the leads (wires). Somewhat incorrectly, TO-5 and TO-39 are often used in manufacturer's literature as synonyms for any package with the cap dimensions of TO-5, regardless of the number of leads, or even for any package with the diameter of TO-5, regardless of the cap height and ...
